• Windows Server 2008 Alerting to Low memory

  - by t1nt1n

  I have a file and print server running on Windows 2008 R2 fully patched in a VSphere environment (ESXi 5.1 fully updated). Every evening between 19:20 and 19:30 our monitoring software reported that the available memory is 1% and performance is dire. There is nothing in the event logs to point to an issue. At this point in the evening I am general the only user on the system to check to see why these alerts are going off. Things I have done; Checked to see if any backups are running – None at all. Checked Scheduled tasks – None before or during this time period. Moved the VM to another host. AV is disabled to rule out that as the issue. The server does not have any problems during the day with memory when fully loaded with about 50 users. The server did have 4GB ram provisioned but I have increased this to 5Gb. Running PrefMon at the time (I will save the graphs tonight) There very little CPU usage at the time but RAM usage goes up.

• Protocol (or service publish/discovery) to detect devices in network

  - by Gobliins

  we connect some embedded devices in a network. What i am looking for now, is a way to find the devices IP and identify them. We work with Windows PC´s and i am about to write a C# tool that should do this. I thought about send a udp broadcast and in the ack i.e. is the device´s ip, which would mean the device needs a daemon runnig to assign an ip itself. Running a service (like a printer) on the device, and on the PC just lookup for the service. I read about some things like apipa, zeroconf, ipv4 local link, bonjour, dns-sd, mdns, bonjour; They can automatically assign ip´s and publish services in a network. My Question is, can someone recommend me what would be good for my task? -The protocol or Service should be low on ressource (memory/cpu usage) use. -Are there some standard protocolls to use? -Is DNS a good idea or would it be to ressource consumpting just for finding a device´s IP? -Should also work when no dhcp servers are around. edit: To clarify a bit: The IP configuration is automatic. The problem to focus is how to tell the PC which IP in the network (or a direct connection in this vase there would only be one) belongs to the device (identity).

• How much Ram should I need on my VPS package? Am I being ripped off?

  - by Tamerax

  Hello! So, I'm currently on a VPSVille Cpanel3 account that has 768 MB guaranteed ram and 2048 MB burst ram (full details here: http://www.vpsville.ca/cpanel-vps). It's running CentOS, Cpanel, Apache and FastCGI. On the server itself I have a joomla community site with a forum system that generally has about 20 people on it max at any point and even then, during the evening, no one. It's a pretty small site but has a number of modules running on it. It gets about 6000 visits a month. Also on the server is a wordpress site that gets about 80-150 visits a day, 2 other wordpress sites that aren't developed yet so they don't get any traffic at all and 2 static html websites that also only get about 500 hits a month. All in all, no huge sites. The issue is that I get "out of memory" errors fairly frequently and it kills my server and I need to reboot it in order to get all my sites up and running again. It seems to me that I shouldn't have these issues with that much ram allotted to my account and everytime I send in a support ticket, they just tell me to upgrade the ram. Now, I'm still pretty new to all this so I'm not a good judge of how much I really need for my sites to run. I don't know if my sites really do need this much OR vpsville has oversold there servers, they don't actually have those resources available and I'm getting ripped off. So, how much ram should I be using with my current setup? Thanks!

• What can cause the system to freeze in a way where even the reset button takes a long time to react?

  - by ThiefMaster

  What can be the reason for system freezes that are so "hard" that even the hardware reset button takes about 3 seconds until it actually resets the system (and then it actually powers down and up again instead of doing a "clean" hard reset like when pressing it during a normally running system). Since it initially happened mainly while playing videos from YouTube I suspected the graphics card - however, I replaced it recently and it did not change it. It still happens from time to time (and sometimes more often, like a few times times in the last few hours). The system is running Windows 7 - but I don't think this matters since I don't think any software, not even the OS, can actually affect the reset button's behaviour. The PC is not overheated and the freezes happen randomly. There is also no malware on the system. The CPU is an Intel Core i7-920 on a Gigabyte EX58-UD5 mainboard. What could be the cause for this problem? Faulty RAM? I did not run a full memtest86 check yet, but I wonder if there is a more likely issue than faulty RAM - checking 12G of ram does take some time after all! There are no entries in the event log - but that's what I expected since the system freezes so hard that I doubt it has time to write anything to any log.

• Computer Turns on Briefly then right back off again.

  - by goddamnyouryan

  So yesterday I came home from work and went to turn my computer on....it turned on for about 5 seconds then promptly turned right back off again...before I ever saw anything on the screen. I tried again, same result. After several attempts, I've found that the length at which it turns on differs. After trying multiple times in a row, it only stays on for about 3 seconds. If I let it rest for a bit it sometimes will stay on for up to a minute (though it never boots, the screen stays black the whole time). I'm not sure what is causing this issue...I built this computer a little more than 2 years ago and this is the first issue I have ever had with it. I did all the usual checks: -It's not the power switch -The capacitors on the motherboard all seem to be in working order -The PSU seems to be fine as it lights up, fan spins, and will sometimes stay on for about a minute period My hope is that the thermal paste on the cpu has degraded and just needs to be re-applied. Does that seem like a reasonable assumption? I'm going to tear the thing apart and do a minimum system build when I get home, but any heads up as to what I should be looking for would be much appreciated. Any thoughts?

• Mysql InnoDB and quickly applying large updates

  - by Tim

  Basically my problem is that I have a large table of about 17,000,000 products that I need to apply a bunch of updates to really quickly. The table has 30 columns with the id set as int(10) AUTO_INCREMENT. I have another table which all of the updates for this table are stored in, these updates have to be pre-calculated as they take a couple of days to calculate. This table is in the format of [ product_id int(10), update_value int(10) ]. The strategy I'm taking to issue these 17 million updates quickly is to load all of these updates into memory in a ruby script and group them in a hash of arrays so that each update_value is a key and each array is a list of sorted product_id's. { 150: => [1,2,3,4,5,6], 160: => [7,8,9,10] } Updates are then issued in the format of UPDATE product SET update_value = 150 WHERE product_id IN (1,2,3,4,5,6); UPDATE product SET update_value = 160 WHERE product_id IN (7,8,9,10); I'm pretty sure I'm doing this correctly in the sense that issuing the updates on sorted batches of product_id's should be the optimal way to do it with mysql / innodb. I'm hitting a weird issue though where when I was testing with updating ~13 million records, this only took around 45 minutes. Now I'm testing with more data, ~17 million records and the updates are taking closer to 120 minutes. I would have expected some sort of speed decrease here but not to the degree that I'm seeing. Any advice on how I can speed this up or what could be slowing me down with this larger record set? As far as server specs go they're pretty good, heaps of memory / cpu, the whole DB should fit into memory with plenty of room to grow.

• Very high Magento/Apache memory usage even without visitors (are we fooled by our hosting company?)

  - by MrDobalina

  I am no server guy and we have issues with our speed so I come here asking for advise. We have a VPS with 2 cores and 2gb of RAM at a Magento specialized hosting company. Over the course of the last weeks our site speed has gotten worse, even though our store is new, has less than 1000 SKUs and not even 100 visitos a day. At magespeedtest.com we only get 1.87 trans/sec @ 2.11 secs each with a mere 5 concurrent users. Our magento log files are clean, we have no huge database tables or anything like that. When we take a look at our server real time stats, we see that the memory usage jumped up from about 34% to 71% and now 82% in just a few days in idle, with no visitors on the site. Our hosting company said that we do not need to worry about that as it`s maybe related to mysql which creates buffers (which are maybe not even actually being used) and what is important is CPU and swap - stats are ok here. They also said that the low benchmark scores are caused by bad extensions or template modifications on our side. We are not sure if we can trust that statement as we only have 4 plugins installed (all from aheadworks and amasty which are known to be one of the best magento extension developers). Our template modifications are purely html and css, no modifications to the php code. Our pagespeed is ranked with 93/100 in firebug and Magento is properly configured, so the problem really just gets obvious when there are a handful of users on the site at the same time. Can anyone confirm our hosting`s statement about memory usage and where can I start looking for a solution?

• How to decouple development server from Internet?

  - by intoxicated.roamer

  I am working in a small set-up where there are 4 developers (might grow to 6 or 8 in cuople of years). I want to set-up an environment in which developers get an internet access but can not share any data from the company on internet. I have thought of the following plan: Set-up a centralized git server (Debian). The server will have an internet access. A developer will only have git account on that server, and won't have any other account on it. Do not give internet access to developer's individual machine (Windows XP/Windows 7). Run a virtual machine (any multi-user OS) on the centralized server (the same one on which git is hosted). Developer will have an account on this virtual machine. He/she can access internet via this virtual machine. Any data-movement between this virtual machine and underlying server, as well as any of the developer's machine, is prohibited. All developers require USB port on their local machine, so that they can burn their code into a microcontroller. This port will be made available only to associated software that dumps the code in a microcontroller (MPLAB in current case). All other softwares will be prohibited from accessing the port. As more developers get added, providing internet support for them will become difficult with this plan as it will slow down the virtual machine running on the server. Can anyone suggest an alternative ? Are there any obvious flaws in the above plan ? Some key details of the server are as below: 1) OS:Debian 2) RAM: 8GB 3) CPU: Intel Xeon E3-1220v2 4C/4T

• Web Server slows down (ASP.NET)

  - by mfeingold

  below is a question I posted on stackoverflow . as suggested by Martin Clarke I also post it here. We have a really strange problem. One of the servers in the server farm becomes really slow. We see a number of timeouts in the logs and overall response time is not where it should be (and is on other servers in the farm). What is also strange is that it is not just the web app - Just logging into the server takes up to 1.5 min to show you the desktop. Once you are in, the system is as responsive as ever - unless you try to launch something, i.e. notepad - it takes another minute to launch and after launch it works fine. I checked a number of things - memory utilization is reasonable, CPU is below 15%, windows handles, event logs do not show anything. Recycling the aps.net process does not fix it - it still takes over a minute to log in. Rebooting the server helped, but now it started to slow down again. After a closer look we found out that Windows Temp directory is full of temp files - over 65k files. This is certainly something to take care of. But my question is could it be the root cause of the sluggishness, or there is still something else lurking in the shadows? Edit After more digging I am zeroing in on the issue related to the size of temp directories. This article: (see the original post this thing will not let me include a second link) describes something very similar. It still does not answer the question why the server is still slow even there is no activity.

• Can I host multiple sites with one Amazon EC2 instance [duplicate]

  - by user22

  This question already has an answer here: Can you help me with my capacity planning? 2 answers I currently have VPS server and I pay around $75 per month and I get: 40GB HD 2Gb RAM 100GB BW 6 core cpu (but i dont use much) I have only one live website running and traffic is only max 100 user visit per day. I mostly do the my testing stuff and some of my inter sites for playing with coding. But I do need one server. I am thinking of moving to Amazon EC2 if the price diff is not so much because then I can learn some more stuff. I am thinking of getting the 3 years Heavy utilization Reserved instance because my server will be running all day and night. I tried their online caluclator with Medium Instance Heavy reserved for 3 years for EC2 it comes $31 per month(effective price) and for EBS and S3 , I think even if thats it $40 for all other stuff. I will be at no loss for what I am getting at present. Am i correct or I missed something?? Now In my current VPS I have Apache for PHP sites and MOD wsgi for python sites. I am not sure if I will be able to do all that stuff in Amazon EC2. Can I host python and PHP sites both in Amazon EC2 instance using Named Virtual Hosts and Ngnix

• HAProxy appsession vs cookie precedence

  - by user1139473

  I am trying to find the best solution for balancing and keeping persistence on our application behind HAProxy. Here is our basic configuration: https://gist.github.com/endzyme/1804046b23c37beba520 After playing around with taking members down and up and also reloading the haproxy (with -sf) I have noticed that appsession isn't 100% effective, it would appear that sometimes it doesn't always 'request-learn'. I also tried to add a cookie JSESSION prefix to balance in case request-learn didn't take. Unfortunately it would present scenarios where the prefix would list svr2 but it was balanced to a different server. I am assuming it's because the appsession table takes first then sticks on that before using the cookie parameter. I have not tested with using cookie as an inserted option (not prefix on existing cookie) but I am thinking it would yield similar results. My question is: Which one is checked first, appsession or cookie, and is it an immediate catch after it reads the first one, or a fall through? Also as a follow up - is it not recommended to use both in the same backend? Cookie as I understand takes less memory resources, is agnostic to reloads and has way better reliability of persistence. Appsession I assume takes less cpu resource, since it's reading not writing. (Bonus Question: is there a way to inspect appsession/cookie table map? socket show table doesn't show anything except stick-tables) Many thanks in advance, -Nick

• Users Password does not reset after successful login at the console but works fine with SSH

  - by jnbbender

  The title says it all. I have my unsuccessful login attempts set to three. I purposefully fail logging in 2x, then when I SSH into the box successfully the 3rd time my count drops back to zero; exactly what should happen. But at the console I get failed login attempts EVEN for my successful login attempts. I am using RHEL 5.6 and no I am not able to upgrade. Here is my system-auth file: auth required pam_env.so auth required pam_tally.so onerr=fail deny=3 per_user auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 500 quiet auth required pam_deny.so account required pam_unix.so account required pam_tally.so account sufficient pam_succeed_if.so uid < 500 quiet account required pam_permit.so password requisite pam_cracklib.so try_first_pass retry=3 password sufficient pam_unix.so md5 shadow nullok try_first_pass use_authtok password required pam_deny.so session optional pam_keyinit.co revoke session required pam_limits.so session [success=1 default=ignore] pam_succeed_if.so service in crond quiet use_uid session required pam_unix.so I have tried adding reset after and in place of per_user in the auth required pam_tally.so field. Nothing seems to work and I don't know why SSH is working just fine. Any ideas?

• Windows 7 "freezes" (chills?), and then "unfreezes" for about 1 minute.

  - by gbc001

  Hi, I have an Acer Timeline 1810T netbook (4GB RAM) with Windows 7 x64. About once or twice a day, it "freezes" - the reason i put this in quotation marks is that it does not really freeze, as in you cant move mouse, etc. I can move my mouse and jump between different applications, but I cant use the applications for anything. So I can jump between notepad and Firefox, but I cant browse to a new web page. I have been trying to determine the source of this misery for a while now, and I suspect it has something to do with the hard drive - indirectly if not directly. Here are some screen shots of the resource monitor during a "freeze" and during normal operation: Freeze: http://imgur.com/Gcgq1.jpg Normal operation: imgur.com/mlHaI.jpg As you can see, CPU is fine during freeze, but the disk is going bananas.. Does anyone have an idea of what these reading mean, or about the problem in general? There seems to be no specific activity that sets this off - it can be during browsing, or during media playback with nothing else open. Very appreciative of any help!

• How can I document and automate a system's configuration?

  - by Diomidis Spinellis

  Having a system's configuration represented by its current state is risky, inefficient, and opaque. At some point you may be left with an unsupported system and no upgrade path. Then configuring a new system compatible with the old is a process or trial and error. Furthermore, if at some point the system is damaged the only option is to go back to the most recent full backup, and try to remember what changes followed from that point. Also, the only way to create a system compatible with the original is through a complete dump/restore. Finally, in such a setup there's no way to know how you solved a particular problem; the only thing you can do is to look at the corresponding configuration files and try to guess what you changed to achieve the desired effect. Currently for each system I maintain, I keep a log file where I record all system administration activity, starting from the installation: installation options, added packages, changes in configuration files, updates, problem fixes etc. In theory this allows me to (manually) replay all changes to arrive at the current state, or to unroll an erroneous change by executing the reverse commands. However, this process is also inefficient, error-prone, and relies on human judgment. Another thing I've tried is to put /etc configuration files under version control with git. This helps me document the changes automatically and also apply them on a clean setup. But it's not without problems: git has to run under sudo, passwords and private keys may be stored in the repository, installed packages can't be meaningfully tracked, and git will have a fit if I try to extend this approach to all the system's directories. I've also thought about performing all changes through shell scripts or makefiles, but I think this process will require a lot of effort and will be fragile. Are there some better methods or tools that I'm missing?

• Mobile app for sysadmins with monitoring and fixing tools(SSH, ping, traceroute) [closed]

  - by Roman

  I present a start-up company which is working on a new mobile tool for system administrators. Our team has released first several versions of Server Auditor which is now just a SSH terminal with special UI approach for touch devices and got quite good feedbacks, e.g. iOS and Android. Now we are thinking about adding extra features to make Server Auditor a tool number one for all system administrators and would like to know your opinion. Main question would you use a tool like Server Auditor with extra features described below: Fast problem fixing - preloaded recipes/snippets, e.g. clean logs, restart a process, reboot etc. Secure user data synchronisation(IP/DNS name, connection options, keys, snippets) across all your devices iPhone and Android. Built-in tools like ping, traceroute, whois System status integration - you can observe information about the system in a friendly way, e.g CPU load, hard drive and RAM usage etc. Monitoring tool integration. Your servers are watched by our Nagios-like system in the cloud and you get notified by push-notifications/SMS. Similar products are Server Density, CopperEgg. If we start to implement features from 1 to 5 when you will be ready to start use it or even potentially pay for it? Can you see any issues that would prevent you from using this kind of system? Thank you a lot for your time, we kindly appreciate it. Looking forward to hear your opinion

• moving from WinXP to WinServer in VmWare

  - by Alex

  I have a Vmware machine for.Net application testing. Current setup: Host OS: win7 Guest OS: Right now the guest OS is Win Xp Pro x64, which runs great with just 1 gigabyte of RAM and 10 gigs of disk space. * This part can be skipped * As I said, there was a program that I needed to test, but unfortunately, by default, Vmware installs crappy display drivers(called SVGA II) on XP machines and there is NO way to upgrade them! This resulted in my program's error (the program used SlimDX (DirectX wrapper) to do some stuff..). Eventually I found out that display drivers most certainly is the problem. For example, Windows 7 virtual machine uses SVGA 3D drivers and I have NO problems running my SlimDX-based program. Now, regarding Windows Server 2008! Apparently, WDDM driver is supported by WS2008, which means that I'll be able to install SVGA 3D and to test my DX apps. * end of skip * The questions are: Will WS2008 be as smooth with just 1 gig of RAM just like Win XP was? Will 10 gigs of HDD be enough? Or the server requires more? Will I be able to install .Net ver. 4 on WS2008? Are there any limitations that I need to be aware of as a .Net programmer? EDIT: I was hoping that WS2008 is XP-based, not Vista-vased/W7-based. In comparison, W7 virtual machine with 2 gigs of RAM and 2 proc cores nearly kills my Host OS. Whereas, WinXp runs extremely fast even with 1 core and 1 gig of RAM. That's the main reason why I want to try WS2008..

• Hp Pavilion dv6000 wont boot right and freezes

  - by MalwareManiac

  I have an hp pavilion dv6000 that was having windows issues recently including randomly freezing. I eventually concluded that the hard drive was bad (And I was correct as the bad drive started making funny noises and quit working soon after). So I replaced it with a known good drive and put windows on it and it worked for a few hours. After a few restarts startup didn't even make it to the login screen. It just stays at a lighted black screen until I restarted. After another restart it made it to windows but then froze after a few minutes. A few more restarts yielded one of these two results. Like I mentioned earlier I have a know good drive in it and I also replaced the memory that was in it with a know good stick along with running memtest with no errors. So What does that leave? a corrupted windows installation? Motherboard? CPU? Any ideas?

• Slow Routing Over LAN (Wired)

  - by reverendj1

  I'm having issues with my router acting very slow (Adtran Netvanta 3458). We have two networks, let's call them A and B. When I run netperf from two servers on network A (no routing) I get speeds along the lines of 900 Mbps. Which makes sense, since we have all 1Gbps switches. When testing A to B (or vice-versa) I get speeds along the lines of 22Mbps. I have also tested connecting my laptop to the switchports on the router, and testing two servers on network A (no routing) and got speeds around 90 Mbps. Which makes sense since the switchports on the router are 100Mbps. Does anyone have any idea why routing would be so slow? We bought the router over a year ago, and we think it has been doing this since then, but we never actually tested it before. (network B isn't really used much, so we didn't notice much) We were implementing a site-to-site VPN and noticed it was ridiculously slow, so we started testing basic routing performance. I have ruled out cabling and router CPU/memory utilization. Adtran looked at my config, but didn't see anything wrong with it.

• Problems with Program startup in WIn 7 this week

  - by PyNEwbie

  I have a program (ISYS) that I have been using since 2006. It migrated successfully to Windows 7. Just yesterday it started manifesting this strange behavior. The program has a selector to allow you to select a directory that might have relevant files for the program. As of yesterday the program will only let me select folders on the C drive. For example I have a folder on D that I need to access with this program - from the GUI when I select the D drive the directory list does not load, instead it churns away using 17% of the CPU cycles. I have let it run for an hour several times. I have found that I can get the directory I want by using a batch file to start the program but this limits my ability to do certain things I really need to use the GUI. I did a number of reboots and other tests - I disconnected drives but once I try to select some directory on a drive other than C it churns away. I have experimented quite a bit and am convinced (which means I am wrong) that this has something to do with some setting change on my computer that I can't figure out as I don't see any updates. Since ISYS has not been updated I feel confident it is something internal. Any suggestions would be appreciated.

• Duplicate monitor on highest resolution in Windows 7

  - by AlexanderMP

  I have a monitor with a native resolution of 2560x1440, connected through display port. I also have an AV Receiver connected to the video card via HDMI, to have surround sound in games. All using Radeon HD 5670 (will upgrade soon to HD 7850). The problem is that my computer detects the receiver as a separate monitor, with the highest available resolution of 1920x1080. I have 3 options: Disconnect the second display. But then the sound (digital audio output through video card) also disappears. Duplicate displays. But then my primary monitor resolution is reduced to a maximum of just 1920x1080, that being the maximum of the second monitor. Extend desktop. This is the solution I picked so far, it being the least evil. The problems I face in this situations are 2: I have a blank part of the desktop where I sometimes lose my mouse pointer, so I made the extension small, 640x480, and placed it in a corner; when I turn off the main display, all windows resize to 640x480. In Kubuntu I had the option to duplicate the displays, while keeping the higher resolution. Which was great. I tried overriding using the Win7 netbook hack, but it's not available on non-netbooks. Is there a similar solution for this problem in Windows 7?

• Computers on network crashing

  - by Phil Cross

  We have recently upgraded our network to Windows 7 clients with Windows server 2008 servers. The upgrade was completed by the end of September and until now has been fine (apart from the minor bugs). Recently (within the last 2 weeks) we've notice all computers on the network (around 1000) start to slow down to the point their unusable. It starts at about 08:45 and finishes at 09:15. Because of this, we think something may be broadcasting across the network. This happens every day, between these times. I cant use my computer at all at the slowdown peak, and looking at task managers performance graphs, Physical memory is hovering around 35% and CPU usage is at 0-10% (idle) yet still crashing. I've looked on DHCPs server log and cant see anything which stands out. The only change we made prior to the slowdown was installing adobe CS6 on some computers, however the slowdown affects computers without CS6. We have 2 physical machines, each with around 5-7 virtual machines running on them with ample memory. Does anyone have any suggestions as to what we can do to narrow down whats causing the crashes? Any help, suggestions or advice would be appreciated.

• why does my dl380 G3 crank the fan up so high (and how do i stop it?)

  - by smoofra

  I've got a HP DL380 and after I leave it on for a while it decides it needs to run the fans at a much higher speed than it did before. It's really loud and annoying. Is there any way to manually control the fan speed? Or otherwise get it to stop doing that? Thanks. edit: I guess i should have made it clear that this is a bit of a jury-rigged situation. I know the ideal solution is to put the thing in a server room with nice cool air. Unfortunately, that isn't happening. This is the sort of problem that calls for a jury rigged solution like manually setting the fan speed and accepting the fact that it's going to run hot shutting down a CPU (can i do that?) spinning down the disks when they're not in use (is that possible?) solution: Install HP's system health monitoring daemon, hpasmd. I installed it to try to figure out what was going on, and just running it fixed the problem.

• Fedora 13 becomes unresponsive when too many applications running.

  - by user61766

  I am using Fedora 13 64bit on Dell Vostro full 4GB RAM system with default Gnome GUI. This is very annoying problem that I don't how to fix except by rebooting the whole PC. When I have too many applications running ( like browser windows), the system start acting sluggish. The fist symptoms appear in Eclipse IDE which becomes so terrible it just becomes frozen for sometime one whole minute after I try to edit something in the editor. Then Firefox seems like it has crashed. Google Chrome becomes very unresponsive as well. All GUI applications including File manager becomes unresponsive. When I check System Monitor, the CPU is still around 20% and memory is at 80% but the system seems getting fried up. This progressively becomes worse until I soft reboot it or if I dont do it evetually the whole system is fried, no response to any keyboard key or mouse and I have to hit the hardware turn off button. I regularly yum update the system but this makes no difference. Please don't tell not to run too many applications because I need those for my work. I thought Linux is well designed Operating System but I am very disappointed so far. Can some one here help ?

• Trouble Starting MySL Community Server on Windows 7

  I have installed Netbeans 7 on my Windows 7. In addition, the MySQL Community Server 5.6.12 is installed with the MSI installer on thesame 7 PC. The MySQL server is integrated with the Netbeans IDE. However , it is not possible to start or stop the MySQL server from the command prompt or the Netbeans IDE. I am only able to start or stop the server from the Windows 7 services tool. Also , it is difficult running SQL queries from the Netbeans IDE even though it shows there is connection with the MySQL server. I have added the my.ini file to the installed directory of the MySQL server , that is : C:\Program Files\MySQL\MySQL Server 5.6 below is the my.ini file : # For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL. [mysqld] # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin # These are commonly set, remove the # and set as required. # basedir = ..... # datadir = ..... port = 3306 # server_id = ..... # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES Any suggestion is welcomed.

• Diagnosing PC crashes (most often while using shared folders or torrents)

  - by Dyppl

  For the last few weeks my PC (pretty old P4 with WinXP SP3) has been crashing randomly. It just suddenly reboots instanteneously. It feels hardware-related but I wasn't able to determine wether it's software or hardware that causes it. I did notice a pattern though: it's more likely to crash when I copy a lot of files over network or have uTorrent running, but sometimes it crashes when I am not doing anything with it. Copying files from it over network causes it to crash in 1 to 10 minutes almost every time. Using torrents causes it to crash every 1-3 hours. With neither or that on it crashes every 24 hours or so. I ruled out the following probable causes: PSU (I bought a new one and turned off most of the drives so the power is sufficient 100%) Bad HDD or interface cable on my SATA disk from which I was originally copying the data over network (bought new SATA cable and later yanked out the HDD completely, PC still crashes without it) Video adapter (AGP slot is now empty, using the onboard VGA at the moment) Network adapter (removed it from PCI, using onboard LAN) CPU (I think: I changed the termopaste and it's temperature is below 50C) RAM (I think: I ran Memtest86 and it didn't show any errors) At the moment I only have only one system HDD and DVD drives, a mouse and a keyboard plugged in. The fact that it crashes most often when I use network extensively makes me think that maybe it's software related (I removed the network adapter from PCI and now am using an onboard one, so network hardware is unlikely to cause problems). I am now pondering system reinstall but it's not a pleasant solution so I decided to ask wether there are better ideas first. If someone can share a good diagnostic tool it would be great because I didn't find anything good. Thanks in advance, I hope that "help to diagnose" questions aren't entirely banned here. EDIT: Motherboard is actually ~4 years old as I replaced it back in 2007
