• Graphics and USB devices freezing soon after OS loads

  - by Andrew

  I run Ubuntu/Windows dual boot. Last night I started the upgrade to Ubuntu 12.04, and my computer has not worked since in either Windows or Ubuntu. Here's what I got when I rebooted after the upgrade, and continue to get every time I boot: Gets to GRUB screen OK. Choose Ubuntu - black screen or crazy purple lines. At first I assumed something went wrong with the upgrade (often happens). Choose Windows - works fine, I log in, but soon after that the graphics freeze (sometimes with purple artifacts). The keyboard and mouse (both USB) also lose power at the same instant, and none of the USB ports have power to them. This happens sooner or later every time I boot. Update: the HDD also appears to lose power at the same point. I have tried a live CD, but my computer refuses to boot any CD even after disabling all other boot options in the BIOS. I have disconnected everything except keyboard, mouse, graphics card with one monitor, one RAM sick and HDD; no change. I also took the little battery out to reset CMOS. I am pretty sure no matter how wrong the Ubuntu upgrade went, it wouldn't cause the above symptoms in Windows. So the only explanation I can think of is that a hardware failure occurred at the same time. Some possible causes of this I can think of are: A couple of days before this, I added a third screen (which worked fine). About a week before, my house lost power in a storm (no ill effects over the past few days though). What can I do, other than buy a new motherboard/CPU and hope it works? Unfortunately I don't have another box to swap parts into to test at the moment.

• Tomcat web application intermittent freeze

  - by tinny

  I have a Grails web application (just a standard war file) deployed on a Ubuntu 10.10 server running on tomcat 6. My database is postgresql. The problem is that every so often (once or twice a day after inactivity) when I try to log into this web application it just freezes. I can navigate to the login page but when I try and login (first time the DB is hit, might be a clue..?) the application just freezes indefinitely, no 500 response code... the browser just waits and waits. I followed the instructions detailed here because the problem described sounded the same as mine. My GC logging showed no long running GC, all sub sec. When the application freezes a jmap heap output is... using parallel threads in the new generation. using thread-local object allocation. Concurrent Mark-Sweep GC Heap Configuration: MinHeapFreeRatio = 40 MaxHeapFreeRatio = 70 MaxHeapSize = 536870912 (512.0MB) NewSize = 21757952 (20.75MB) MaxNewSize = 87228416 (83.1875MB) OldSize = 65404928 (62.375MB) NewRatio = 7 SurvivorRatio = 8 PermSize = 21757952 (20.75MB) MaxPermSize = 85983232 (82.0MB) Heap Usage: New Generation (Eden + 1 Survivor Space): capacity = 19595264 (18.6875MB) used = 11411976 (10.883308410644531MB) free = 8183288 (7.804191589355469MB) 58.23843965562291% used Eden Space: capacity = 17432576 (16.625MB) used = 9249296 (8.820816040039062MB) free = 8183280 (7.8041839599609375MB) 53.05754009046053% used From Space: capacity = 2162688 (2.0625MB) used = 2162680 (2.0624923706054688MB) free = 8 (7.62939453125E-6MB) 99.99963008996212% used To Space: capacity = 2162688 (2.0625MB) used = 0 (0.0MB) free = 2162688 (2.0625MB) 0.0% used concurrent mark-sweep generation: capacity = 101556224 (96.8515625MB) used = 83906080 (80.01907348632812MB) free = 17650144 (16.832489013671875MB) 82.62032270912317% used Perm Generation: capacity = 85983232 (82.0MB) used = 62866832 (59.95448303222656MB) free = 23116400 (22.045516967773438MB) 73.1152232100324% used Anyone know what "From Space:" is?

• High load without explanation

  I have a very high load on my machine and don't know what is responsible or how to find out. On the machine runs a jboss appserver and mysql. Here is a top from the user at peak time: top - 16:23:01 up 101 days, 6:50, 1 user, load average: 23.42, 21.53, 24.73 Tasks: 9 total, 1 running, 8 sleeping, 0 stopped, 0 zombie Cpu(s): 17.2%us, 1.6%sy, 0.0%ni, 80.4%id, 0.1%wa, 0.1%hi, 0.7%si, 0.0%st Mem: 16440784k total, 16263720k used, 177064k free, 151916k buffers Swap: 16780872k total, 30428k used, 16750444k free, 8963648k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 27344 b 40 0 16.0g 6.5g 14m S 169 41.7 1184:09 java 6047 b 40 0 11484 1232 1228 S 0 0.0 0:00.01 mysqld_safe 6192 b 40 0 604m 182m 4696 S 0 1.1 93:30.40 mysqld 7948 b 40 0 84036 1968 1176 S 0 0.0 0:00.07 sshd 7949 b 40 0 14004 2900 1608 S 0 0.0 0:00.03 bash 7975 b 40 0 8604 1044 840 S 0 0.0 0:00.44 top The CPU usage of the java process is normal.

• Error loading operating system: format Windows 7 to Windows XP Service Pack 3

  - by Blerta

  I saw that there are other questions like mine here. But O also saw that some problems where solved with fixmbr from a Windows 7 recovery console, but that didn't work for me. I bought my laptop with Vista installed and later reformated and used Windows 7. During formatting with Windows 7 I had some problems with my hard drive and found out it was dead so I bought a new one. I wanted to reformat with Windows XP,because Windows 7 is consuming more RAM that it is able handle and I wanted to use it for other programs. So I formatted with Windows XP Service Pack 3 but after first reboot a message appeared: "Error loading operating system" Reading here, I assumed that maybe I had installed it on the wrong partition and maybe having two OS now, so I used fixmbr but it is still not starting up. Anyway I am sure that is not the case of two operating systems. Is there any chance that when the computer designed to work with Vista you would face problems with Windows XP? Like not recognizing a hard drive?

• Poor Write Performance in VM inside Proxmox PVE 2.0

  - by sorsenne

  I am running a PVE 2.0 on a decent Hardware (2 SATA HDDs as RAID1, 12GB RAM, i7 CPU) but the I/O Performance is very poor inside the VM (Ubuntu 11.10 Server). The very same VM was copied to another Server running simply Ubuntu Server with KVM and had better I/O Perf. this is how the HDD is shown in the Guest: ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300) ata1.00: ATA-8: ST3000DM001-9YN166, CC49, max UDMA/133 ata1.00: 5860533168 sectors, multi 16: LBA48 NCQ (depth 31/32), AA ata1.00: configured for UDMA/133 scsi 0:0:0:0: Direct-Access ATA ST3000DM001-9YN1 CC49 PQ: 0 ANSI: 5 sd 0:0:0:0: [sda] 5860533168 512-byte logical blocks: (3.00 TB/2.72 TiB) sd 0:0:0:0: [sda] 4096-byte physical blocks sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA I tested with DD: $ dd bs=1M count=128 if=/dev/zero of=test conv=fdatasync 128+0 records in 128+0 records out 134217728 bytes (134 MB) copied, 19.2222 s, 7.0 MB/s on the Host, this same Test will result with 156 MB/s in average.

• New XPC: No video, no ethernet link, but drive spins

  - by Mike Pennington

  I bought a Shuttle XPC SH67H3 with integrated video. I installed: An Intel i5 2450P 16GB DDR3 RAM A SATA hard drive from my old linux server that still is bootable I have both power connectors plugged into the motherboard. I realize that the Intel i5-2450P doesn't have video capabilities; however, the drive spins like it's doing something useful. It seems like I should get an ethernet link light when I fire this up. I plan to run this headless anyway, so it would be really nice if I could figure out how to run this without a video card at all. I know the IP address and login info for the linux install on the disk. I plugged in speakers, but get no bios beeps when I power it up. Shuttle's bios manual has nothing in there that indicates I should have problems in this configuration. My questions: Is there a reason that the missing video card would block usage of the ethernet port? Are there settings on the motherboard / bios I can change to get this working?

• Cisco Catalyst 3750 connected to Cisco ASA 5505 and dropping packets

  - by Bo102010

  (Cross posted from Super User per suggestion there) At the office, I have inherited a network that I am still trying to fully comprehend. I have a problem today with a new connection between: A port on a Cisco Catalyst 3750 [WS-C3750G-48TS-S running C3750-IPSERVICESK9-M version 12.2(53)SE1] A port on a Cisco ASA 5505 [ASA Software version 8.3(2)] The 3750 is home to a Vlan that has a few ports assigned to it. interface Vlan3 description Internal network (172.18.160.0/24) ip address 172.18.160.1 255.255.255.0 I have a host (outside of my control) that needs to be in this VLAN (i.e it must have an address 172.18.160.something/24) that also needs to access the Internet. To accomplish this, I ran a link from the Catalyst (Gi1/0/13) to the ASA (Ethernet 0/5). I configured the Catalyst port like so: interface GigabitEthernet1/0/13 description To ASA, 172.18.160.69 switchport access vlan 3 switchport mode access speed 100 duplex full I configured the ASA like so: interface Vlan1 nameif inside security-level 100 ip address 172.18.160.69 255.255.255.0 interface Ethernet0/5 speed 100 duplex full Then I plugged the host into Ethernet 0/4 on the ASA and instructed its owner to make its default gateway 172.18.160.69. I made a NAT rule in the ASA and set up some rules, and it's able to access the Internet without issue. However, I noticed that the Catalyst reports a ton of packets being dropped toward the ASA. Catalyst3750#show interfaces GigabitEthernet 1/0/13 | include counters|drops Last clearing of "show interface" counters 00:28:13 Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 136909347 This is a huge number of drops, since there's not much traffic on this VLAN at all. I tried these things: Make sure speed and duplex agree on both sides (100 Mbps / Full) Set no cdp enable on the Catalyst Gi10/13 Set no keepalive on the Catalyst Gi10/13 Checked for excessive CPU usage on both Checked for excessive traffic on both Am I missing something? Any help would be appreciated.

• "The directory name is invalid" when trying to install drivers in Windows 7 via Device Manager

  - by Luke

  First off, this computer is not mine, it's a customer's system. Having said that... The hard drive was moved to a new motherboard, CPU, RAM combo, and booted up fine. Customer puts in driver CD, drivers won't load. He brings it into me. Under Device Manager for Windows 7 x64, I see lots of PCI to PCI bridge, one SMBus Controller, and about 20 Unknown Devices. Greeeeeat... So I start with the SMBus driver directly from the Asus website for the motherboard (P8H77-M Pro). If I install from the setup program, it tells me to reboot, then it starts the install. It gets half way through the setup, then fails (An unknown error occurred. Setup will exit). When I try to point to the folder from Device Manager, it starts copying files for the driver, even presents me with the proper name of the device, but says that an error has occurred there as well: The directory name is invalid. Doing some Googling, I saw that many people had this issue with Vista. K, Vista and 7 are similar, maybe the solutions are the same... But they aren't. I tried: Copying the entire driver folder and setup utility to the Program Files folder and running it / selecting it in DM Downloading another set of drivers in case this one is corrupt Disabling UAC Deleting and recreating the %WINDIR%\TEMP folder Removing all references to previous hardware that I could find, even in Device Manager's hidden mode So far, nothing has worked. A wipe and reload will be out of the question

• Error occurs when Win 7 opens

  - by user1708748

  I have an HP customized laptop barely a week old. Since yesterday it has given me an error message while opening Windows- every time. it gives error code (0x40000015) refers to an exception at location (0x0033fa4d). I have 64 bit Win 7 and had been transferring files. And installing programs. 8 GB Ram 650 gb hard drive. Not sure which program caused this. Q's that I've seen with this error code all say it occurs while shutting down. A search re. error code told me to use a removal tool. When I downloaded the tool,I got a message saying it is not compatible with Windows 7. Is that really possible? Search re. location code yielded nothing I am an intermediate user. I can restore to an earlier time but I don't know which program might do this again.

• Tuning Windows 7 for use in a VM

  - by intuited

  I'm running Windows 7 in a VirtualBox Virtual Machine, and would like to make it run in a more streamlined fashion. I'll be using the install primarily for testing web apps, and have no need for it to run quickly. I would like it to run with minimal memory requirements, and with minimal changes to its virtual hard drive's contents. Changes to the hard drive contents, for example the paging file, result in larger snapshot sizes. Another recent post of mine seems to be related to this issue, but does not directly address issues with Windows. One concern that I have is that Windows seems to be using 17% of its paging file even with over 900MB of memory marked "Standby" or "Free". My uneducated guess is that this is being used to store indexes or some other data that helps to speed up the system but is not really necessary. I'm also wondering if it's normal for Windows to use over 500 MB of "In Use" memory with no apps running. Will this amount decrease if I reduce the amount of "installed" memory in the VM? What steps can I take to reduce the system's memory footprint without incurring an increase in paging file usage?

• Ubuntu 12.04 froze during update, won't boot

  - by Cichol

  I've recently installed Ubuntu 12.04 on my laptop, and every time i tried to update it, it would freeze for a few seconds, and tell me that the updates could not be downloaded. After many, many tries I managed to get them downloaded, but then in the middle of installing them, it froze. Completely. No mouse movement, no blinking lights, no nothing. After a few hours of letting it sit there, I finally hit the power button to do a hard reset, and now when I select Ubuntu on the boot screen (Dual-boot with Windows 7), I get a blank purple screen, and then nothing. Another freeze. I've tried getting into the console, but no command I input has any visible effect. I have a ton of music stored on the partition it's in, so I'd really rather not have to reinstall. My specs, to the best of my knowledge: Clevo Corp model B7130 (Sager custom) CPU: Intel Core i5 @ 2.53gHz (4 CPUs) Graphics Card: Nvidia GeForce 425m 4096 MB RAM Drivers: Whatever comes with the download of 12.04. As a side-note, I installed Ubuntu via the Windows Installer program (wubi). Does that make a difference?

• Diagnosing linux issues with ipod syncing in Ubuntu

  - by alexpotato

  Issue: I am currently using Ubuntu 9.10 with a 5th generation Ipod 60 GB Black video classic. In general, it seems that Ubuntu can always detect the usb hd and displays it on my desktop. However, some applications seem to detect the ipod (e.g. Rythymbox and gtkpod do but Banshee does not) and some don't. I narrowed down the banshee issue to a bug that requires Nautilus to be restarted (although it would be nice to not have to do this). Also, Whenever I sync between these applications, it appears that everything is working fine during the sync but when I disconnect the ipod and browse, all of the songs seem to be there but the playlists are not. If I reconnect the ipod, in banshee specifically it sees the space usage as "other". What I am looking for is some way to at least understand what is and is not working OR directions to some where that can help me learn what's going on. I have already tried: -IRC. Either the channel is too general (e.g. #ubuntu) or no one is ever one (e.g. #banshee) -The web. Most of what I've found is too specific to one particular bug or too general. Any thoughts?

• Mysql can not resolve hostnames when checking privileges

  - by Fabio

  I'm going crazy to solve this. I have a mysql installation (on machine db.example.org) which doesn't resolve a given hostname. I gave privileges using hostnames i.e. GRANT USAGE ON *.* TO 'user'@'host1.example.org' IDENTIFIED BY PASSWORD 'secret' GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, INDEX ON `my_database`.* TO 'user'@'host1.example.org' However when I try to connect using mysql -u user -p -h db.example.org I obtain ERROR 1045 (28000): Access denied for user 'user'@'192.168.11.244' (using password: YES) I already checked for correct name resolution in the dns system: $ dig -x 192.168.11.244 ;; ANSWER SECTION: 244.11.168.192.in-addr.arpa. 68900 IN PTR host1.example.org. I've also checked for skip-name-resolve option in mysql variables in fact if I can access from another machine on the same subnet using hostname privileges. The only difference is that host1.example.org and db.example.org point the same ip on the same machine i.e. both db.example.org and host1.example.org have ip 192.168.11.244. In this way all the applications using that database can use the name db.example.org and we can move the data on other hosts (if needed) just by changing the dns record, leaving the application code unchanged. What should I do to solve this or at least to understand what's happening?

• Least CPU intensive way of streaming your screen on windows?

  - by sinni800

  Hello, sometimes I like capturing my screen for others to see. Only thing: I am playing games while I do it. I have tried a few streaming solutions where Windows Media Encoder coupled with my own Windows server appealed to me most, because I can change resolutions, etc. I also tried ustream coupled with the Flash applet and the Adobe Flash Encoder recording a Camtasia source. Camtasia has the disadvantage though that it shows the green-and-black-alternating borders and can not be targeted fullscreen. I like how xfire does it. But it doesn't work with every game, many are simply not supported. A few thoughts about this: Is there a program which captures like Fraps or XFire (based on Direct3D and OpenGL outputs) and exposes the output to a DirectShow source filter? Which brings me to: Is there hardware accelerated capturing directly from the graphics card? Maybe including direct encoding with help from OpenCL? Modern graphic cards decode BluRay content directly for example. I should have a modern enough graphics processor for this to be possible (see below). If using Windows Media Encoder: Which are the least CPU intensive settings? Which codec? Is there a newer codec than Windows Media 9? Is it less CPU intensive? I only have 7, 8 and 9 inside the Encoder Could the performance be massively increased by having a Quad-Core CPU (see below)? Bandwidth is no problem up to 1000 to 1500 kbit/s (I have 2048). My Computer specs: Intel Core 2 Duo E8400 4 GB DDR2-800 Ram Ati Radeon HD5770 Using Windows 7 Professional

• How will I support 100,000 requests an hour?!

  - by tylerl

  I know this question is a little strange but I got lucky with an idea and I need some numbers to use for when I try to make a deal with a company. I'm wondering how much it'll cost me to run a site that's heavy on PHP and gets between 70,000 and 100,000 requests an hour on something like Rackspace's Cloud Servers. I have no idea how many servers I need or how much RAM each one should have. There will be a decent number of images on the site (probably something like 10,000 in the first couple weeks) and the site runs on about 2,500 lines of PHP code. I figure I should sign up for a CDN of some kind, although CDN In A Box is all I've heard of and I'm not sure it's necessary for a site that's already on a cloud platform. I've obviously never done anything like this before so I'm just looking to get an estimation of what I need for this massive site... Also, I use a database and I was wondering how that works - would I dedicate one of the cloud servers to running the database or would I need to put the database into each of the cloud servers? Thanks in advance...

• Nginx proxy with Redmine SVN authentication.

  - by Omegaice

  I am attempting to setup a system where I have an nginx server running as a reverse proxy for multiple websites that I want to run. To separate the websites I have created a Linux container which contains each site to allow me to reduce conflicts in database usage etc. I am currently trying to get my main site working and have nginx with passenger setup and connecting to redmine and I have an Apache install specifically setup for serving the SVN over HTTP and am attempting to use the redmine authentication with that. I have set everything up as described in the redmine howtos, but when I check a project out from the SVN it always works even if the project is private and whenever I try and commit to the repositories it fails saying "Could not open the requested SVN filesystem", the Apache error log related to that event is "(20014)Internal error: Can't open file '/srv/rcs/svn/error/format': No such file or directory". If I take out the redmine authentication I can checkout and check-in repositories fine but there is no authentication. Does anyone have any ideas? Edit I tried to solve this problem another way by attempting to have the authentication work by LDAP, I managed to get it so that my user could log into the redmine website but as soon as I tried to check anything out it said that access was forbidden to the repository.

• How to start a s3ql script automatically on boot?

  - by ks78

  I've been experimenting with s3ql on Ubuntu 10.04, using it to mount Amazon S3 buckets. However, I'd really like it to mount them automatically. Does anyone know how to do that? I've been working on a script, which works when its run from from the commandline, but for some reason I can't get it to run automatically on boot. Does anyone have any ideas? Here's my script: #! /bin/sh # /etc/init.d/s3ql # ### BEGIN INIT INFO # Provides: s3ql # Required-Start: $remote_fs $syslog # Required-Stop: $remote_fs $syslog # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Start daemon at boot time # Description: Enable service provided by daemon. ### END INIT INFO case "$1" in start) # Redirect stdout and stderr into the system log DIR=$(mktemp -d) mkfifo "$DIR/LOG_FIFO" logger -t s3ql -p local0.info < "$DIR/LOG_FIFO" & exec > "$DIR/LOG_FIFO" exec 2>&1 rm -rf "$DIR" modprobe fuse fsck.s3ql --batch s3://mybucket exec mount.s3ql --allow-other s3://mybucket /mnt/s3fs ;; stop) umount.s3ql /mnt/s3fs ;; *) echo "Usage: /etc/init.d/s3ql{start|stop}" exit 1 ;; esac exit 0

• Updated XAMPP with MySQL, all my tables are missing

  - by user371699

  I just updated XAMPP to a newer version, which included updating MySQL from 5.5 to 5.6. Using phpMyAdmin, however, all of my tables within my databases still appear on the left navigation panel, but the main window shows that all my databases are empty (except for information_schema, and a couple other default tables.) Clicking on a table in the navigation panel gives me a "table doesn't exist" message. It does looks like information_schema.tables doesn't have my tables, either. Can anyone assist me with this? I did make a complete backup of all my databases before the upgrade, but I first want to see if I can fix this the "normal" way. Furthermore, I'm not sure if the MySQL upgrade involved making changes to the information/performance databases, so I don't know if I can restore the old ones. Thank you. EDIT: Continuing my searching, I realized that only the INNODB databases are missing. I've tried running the following with no avail: /opt/lampp/bin $ sudo ./mysql_install_db --basedir=/opt/lampp and /opt/lampp/bin $ sudo ./mysql_install_db --basedir=/opt/lampp --datadir=/opt/lampp/var/mysql The my.cnf file in /opt/lampp/etc contains the following InnoDB settings: innodb_data_home_dir = /opt/lampp/var/mysql/ innodb_data_file_path = ibdata1:10M:autoextend innodb_log_group_home_dir = /opt/lampp/var/mysql/ # You can set .._buffer_pool_size up to 50 - 80 % # of RAM but beware of setting memory usage too high innodb_buffer_pool_size = 16M # Deprecated in 5.6 #innodb_additional_mem_pool_size = 2M # Set .._log_file_size to 25 % of buffer pool size innodb_log_file_size = 5M innodb_log_buffer_size = 8M innodb_flush_log_at_trx_commit = 1 innodb_lock_wait_timeout = 50 What could possibly be wrong? Why is the information_schema not updating correctly? It looks like /opt/lampp/var/mysql has all my tables in it within the database directories, but they're still not showing up in information_schema.

• Laptop will not boot

  - by WillumMaguire

  This is a dell studio 1558 laptop. Now, something is wrong with the charger that it won't charge the laptop, but the laptop can turn on and operate properly as long as it is attached. It has been like this for a while, but it's not the problem. My problem is that as of yesterday, It takes several minutes to get past the "dell" startup logo (where is says "f2 setup" and "f12 boot options"). After it gets past, it beeps as normal to tell me about the charger and gives me the f2/f12 options and f1 to continue as normal. I can press f12 to get into boot options and load into my live USB BackTrack 5 ISO, but after "startx" it just stays at a black screen. I can also access BIOS setup, but see nothing that would help the problem. When I boot to the HDD, it gives me this Intel UNDI, PXE-2.1 (build 083) Realktek PCIe GBE Family Controller Series V.2.29 (06/30/09) PXE-E61: Media test failure, check cable PXE-M0F: Exiting PXE ROM Operating System not found Also, pressing f8 gives me the same results as booting as normal. It is running Windows 7 Ultimate, dual-core Intel i3 @ 2.27ghz and 4gb RAM. I think there is an issue with the HDD, as the "Operating System not found" would lead me to believe. Is this a fixable problem?

• 32bit SQLServer with AWE NOT enabled. Buffer Cache Hit Ratio High, Disk Read Queue VERY HIGH, WHY?

  - by chenwq

  We have a "SQLServer 2005 SP3 32bit Enterprise Edition" running on a 32 bit Windows 2003 32bit Enterprise Edition 12GB RAM with AWE enabled using RAID5(5 pysical disks). We tuned AWE to enabled and restart sqlserver this afternoon after work, hope the performance will be better than old time. But there is something that we are very confused. On working days, SQLServer has a very bad performance. When we are looking for reasons, we check Windows Performance counter. Avg. Disk Read Queue Lenght > 140 Avg. Disk Write Queue Length < 1 SQL Server Buffer Cache Hit Ratio > 96% %Processor Time < 30% SQL Server Total Server Memory < 1.8G Obviously, without AWE enabled, SQL Server can use only less than 2G memory. My Question is: why "SQL Server Total server Memory" is less than 2G?I think SQL Server will use all 2G process address space. Does this counter count anything out? we known that sql server is sufferring lack of memory, but why "buffer hit ratio“ is as high as 96? Any advice is welcomed!

• Chipset fan on the frtiz - compressed air hasn't fixed anything - is there anything I can do?

  - by Anthony

  Yesterday, my computer started to make an annoying whining noise. Knowing that this is likely a fan issue, I opened the case and proceeded to determine which fan was causing the issue. I got some compressed air and tried cleaning out the dust around it (and the rest of the computer while I was at it). This hasn't seemed to fix the issue. Now, if it were just any fan, I would probably just replace the fan - they're relatively cheap after all. However, this is a special fan. Aside: For what its worth, I feel bad that the graphics card blocks part of the fan, but it is the only slot the graphics card fits, so I had no choice. After pulling out my motherboard user guide, it looks like this is a fan placed directly on top of the chipset. To be perfectly honest, I have no clue what the purpose of the chipset is - but it sounds important. After some quick research, I see that it is responsible for providing the bridge between my CPU, RAM and graphics, among other things. Just a quick search at Newegg tells me that chipset fans can be purchased at pretty reasonable prices (< 20 dollars). Is it practical to replace this fan? It is an old computer as computers go and I wouldn't be terribly upset to upgrade the motherboard and processor, so perhaps this is a sign.

• Windows 7 64bits installation via USB asks for drivers

  - by Shikiryu

  I just bought a new config ( ASUS p8z68-v lx, i5-2500k + ram and new graphic card ). Coming back and installing it in my old computer, I just saw that my DVD player was on IDE (yup…). So, I needed to install windows 7 64bits from my usb key. Fine, I made my usb key bootable and copy the official DVD on it (the same version that was on my old computer), set BIOS to boot on it first and started the computer up. It worked fine until it asks me for cd/dvd drivers (which is funny since, I do it via USB because I can't plug in my DVD player :D) I have 3 SATA HDD plugged in and that's it. I made a small google search and found that it could be SATA or RAID drivers. Fine, I took another USB KEY and put all my motherboard drivers on it (from the CD sold with the MB) and none of those drivers seemed to work. I tried downloading new drivers from ASUS website and same effect. Any idea but no "buy a new DVD player", I'm now broke for the month :) ?

• 32 core (each physical core) 2.2 GhZ or 12 core (6 physical cores) 3.0GHZ?

  - by Tejaswi Rana

  I am working on a multithreaded application (Forex trading app built on C#) and had the client upgrade from the 12 core 3.0GHZ machine (Intel) to a 32 core 2.2 Ghz machine (AMD). The PassMark benchmark results were significantly higher when using multicores doing Integer, Floating and other calculations while for a single core calculation it was a bit slower than the pack (others that were being compared to with similar config as the 12 core one). Oh it also comes with 64 GB RAM (4 times as the other one) and a much faster SSD. So after configuring and running the application on that machine, not only did it not perform as well, it was significantly slower. We're talking about 30seconds - 1 minute slower on an app that usually completes processing within 5-20 secs. The application uses MAX DEGREE of PARALLELISM (TPL) which I've tried setting to number of cores and also half of that. I've also tried running single threaded and without setting any limits in parallel threading. While it may be the hardware has some issues, I am wondering if the CPU processing speed is the issue. I can overclock to 3.0 GHZ. But is that even a good idea? Server Info - AMD http://www.passmark.com/forum/showthread.php?4013-AMD-Dual-6272-performance-is-60-lower-than-benchmarks Seems that benchmark was wrong to start with - officially.

• Redundant OpenVPN connections with advanced Linux routing over an unreliable network

  - by konrad

  I am currently living in a country that blocks many websites and has unreliable network connections to the outside world. I have two OpenVPN endpoints (say: vpn1 and vpn2) on Linux servers that I use to circumvent the firewall. I have full access to these servers. This works quite well, except for the high package loss on my VPN connections. This packet loss varies between 1% and 30% depending on time and seems to have a low correlation, most of the time it seems random. I am thinking about setting up a home router (also on Linux) that maintains OpenVPN connections to both endpoints and sends all packets twice, to both endpoints. vpn2 would send all packets from home to vpn1. Return trafic would be send both directly from vpn1 to home, and also through vpn2. +------------+ | home | +------------+ | | | OpenVPN | | links | | | ~~~~~~~~~~~~~~~~~~ unreliable connection | | +----------+ +----------+ | vpn1 |---| vpn2 | +----------+ +----------+ | +------------+ | HTTP proxy | +------------+ | (internet) For clarity: all packets between home and the HTTP proxy will be duplicated and sent over different paths, to increase the chances one of them will arrive. If both arrive, the first second one can be silently discarded. Bandwidth usage is not an issue, both on the home side and endpoint side. vpn1 and vpn2 are close to each other (3ms ping) and have a reliable connection. Any pointers on how this could be achieved using the advanced routing policies available in Linux?

• Find out which task is generating a lot of context switches on linux

  - by Gaks

  According to vmstat, my Linux server (2xCore2 Duo 2.5 GHz) is constantly doing around 20k context switches per second. # vmstat 3 procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 2 0 7292 249472 82340 2291972 0 0 0 0 0 0 7 13 79 0 0 0 7292 251808 82344 2291968 0 0 0 184 24 20090 1 1 99 0 0 0 7292 251876 82344 2291968 0 0 0 83 17 20157 1 0 99 0 0 0 7292 251876 82344 2291968 0 0 0 73 12 20116 1 0 99 0 ... but uptime shows small load: load average: 0.01, 0.02, 0.01 and top doesn't show any process with high %CPU usage.

Any idea how to dig a little deeper for an answer?
