• Commit charge peak higher than system limit

  - by Grubsnik

  We are seeing some very strange behaviour on our servers and google didn't turn up anything usefull, so I'm tossing it out here. A standard server is configured with 4GB Ram, 2 4GB pagefiles and running windows server 2003. The servers are running 50-120 vb6/.net applications which normally consume no more than 100mb of memory, but will occasionally run up to 300 mb. The issue with a single process spending way too much memory is being traced down somewhere else, but the thing that is baffling us is that the reported peak charge is vastly higher than what we have available. As the image above shows, we are getting reported peaks that are way higher than what the system is actually capable of delivering. This number has been seen as high as 29GB, which makes no sense at all for a system with a limit of 12GB. Does anyone have an idea what is going on?

• Why does my company's software download get blocked by anti-virus programs when downloading from the company website but not other websites?

  - by Adam Burgess

  My company distributes software via website download off of a URL that is on our company's website. The download is an .EXE. We are getting calls from multiple customers saying the download is being blocked. We can help them download by turning off the virus-scan software, but wondering what is causing the block. Here are the details: We have other downloadable .EXEs that download fine without being blocked from the same company website. Our problem download file downloads fine from other websites (i.e., Dropbox) without being blocked. In summary, this one particular download from our company website is being blocked by various anti-virus programs a high percentage of the time. Any suggestions?

• AWS: Should my EC2 and RDS instances be in the same Availability Zone?

  - by DOOManiac

  I just noticed that all of our EC2 instances are in zone us-west-2b, but our Multi-AZ RDS instance is in us-west-2a. Performance-wise everything seems to be okay, and it will be a hassle to "move" the instances to one place since you have to stop and re-create them all. However if either of the two zones goes down when we will have some downtime; if everything is in one zone then at least we have a higher chance of not being in the zone that has downtime... Is this something worth fixing, or am I over-thinking it? (I was about to purchase some EC2 Reserved Instances, which are tied to specific AZs, so I wanted to make sure before going through with it) Thanks!

• Disable RAID Controller

  - by B.Mr.W.

  I have some decent HP Proliants server that come with "HP Smart Array P410i Controller" enabled, I am using these boxes to set up a Hadoop cluster and I know, RAID is for sure a no-no for Hadoop since the application itself will take care of data redundancy and extra intelligence provided by RAID won't be helpful and might turn down the performance. I tried to disable the devices at the BIOS and the box cannot even access the disk afterwards. So I am assuming the controller is sitting between disks and mother board, and we have to turn it on and configure it to "level0" or something like that. I am wondering what should I do to "disable" the RAID functionality so it will fit into the Hadoop environment.

• Server 2012 Storage Pools, Raid Controller... can the Storage Pool deal with it?

  - by TomTom

  Before trying it out - I don't find any documentation. Given that Storage Pools have serious performance problems with parity, and do not rebalance data at the moment when you add discs, my preferred way to use them would be as think provisioned space, ISCSI targets - with every "Pool" running against 1 RAID that comes from a Raid controller (who also introduces SSD read and write caching - another thing missing from Storage Pools). The main question is - how does a Storage Pool handle the change in the underlying disc that can happen? I mostly talk about OCE (Online Capacity Expansion), where a disc after an expansion suddenly reports a larger space. Standard Windows allows you to use this additional space (and expand the partitions). How does a storage pool handle it?

• What kind of SSL certificate do I need?

  - by Christoffer

  Hi, I want to install HTTPS on my server and I wonder what kind of certificate I will need and where I can buy it. The site is a web application that demands high security by it's users since they store sensitive business data. I am also integrating a third party payment gateway into the register process of the site and need a secure way to send credit card data one way. I do not intend to store this data in our own database. So, what do I need? And also, how do I install it on Ubuntu Server 9.10 / Apache2 ? Cheers! Christoffer

• How to troubleshoot latency between 2 linux hosts

  - by Jimm

  The latency between 2 linux hosts is about .23ms. They are connected by one switch. Ping & Wireshark confirm the latency number. But, i dont have any visibility into what is causing this latency. How can i know if the latency is due to NIC on host A or B or the switch or the cables? UPDATE: The .23 ms latency is bad for my existing application, which sends messages at very high frequency and i am trying to see if it can be brought down to .1ms

• GPU Computing - # of GPUs supported

  - by TehTypoKing

  I currently have a desktop with 6 GPUs ( 3x HD 5970s ) in non-crossfire mode. Unfortunately, it seems that Windows 7 64bit only supports up to 4 GPUs. I have not been able to find a reliable source to deny or confirm this. If windows 7 has this limitation, is there a Linux flavor that supports more than 4 GPUs? In-case you are wondering, this is not for gaming but high-speed single precision computing. With this current setup ( if I can find 6gpu support ) I am looking to reach 13.8 Teraflops. Also, my motherboard does support 3 16x pci-xpress gen2 slots... and I have a 1500w powersupply plugged into a 20amp outlet. Windows is able to detect all 6 cores.. although, 2 of which displays the warning "Drivers failed to load". To recap: - Can windows support 6 GPUs? - If not, does Linux? Thank you.

• using munin-plugins-rails to monitor rails app perfromance

  - by user2099762

  I have been trying to configure munin-plugins-rails to monitor the performance of our rails apps from Munin. The graphs appear, but no data is shown in the graphs. The log files show Error output from : 2013/06/27-15:39:06 [5540] Request-log-analyzer, by Willem van Bergen and $ 2013/06/27-15:39:06 [5540] Website: http://railsdoctors.com I have tried running Request-log-analyzer manually and pointing it at the production log file, and this reports as % for every item. There is data in the log file. I have tried changing the version of the gems installed, and also the type of the log file, but no luck. Any ideas anyone? Thanks

• Wordpress Installation on Two Servers - Loadbalancing

  - by rihatum

  Hi All, I have to install wordpress (One Blog, one domain, for e.g. mycompany.com/blog) on two servers sharing one database on a different server, these two servers are behind a loadbalancer and the db would be on another server. We are planning this way due to high traffic. I have done standalone wordpress installations on a single server, on windows 2003, 2008 with IIS6, 7 etc I am just researching as to how would I implement this. What would be the steps to achieve this and upon searching I saw some posts regarding the wp-content/uploads directory to be synced at regular intervals ? your help much appreciated Thanks for reading

• How to make VIM settings computer-dependent in .vimrc?

  - by Paperflyer

  I share my VIM configuration file between several computers. However, I want some settings to be specific for certain computers. For example, font sizes on the high-res laptop should be different to the low-res desktop. And more importantly, I want gVIM on Windows to behave more windowsy and MacVim on OSX to behave more maccy and gVIM on Linux to just behave like it always does. (That might be a strange sentiment, but I am very used to switch mental modes when switching OSes) Is there a way to make a few settings in the .vimrc machine- or OS-dependent?

• Running out of LowMem with Ubuntu PAE Kernel and 32GB of RAM

  - by magneticMonster

  I'm running a Java data import process on a 32-bit Ubuntu 10 PAE kernel machine. After running the process for a while, the oom-killer zaps my Java process. After some Googling and digging through docs, it looks like the system is running out of LowMem. I started the process for the third time and am watching free -lm show me Low: 464 386 77 with the free value (77MB) slowly decreasing. Why am I running out of lowmem and how do I increase it? Some details: $ cat /proc/sys/vm/lowmem_reserve_ratio 256 256 32 $ free -lm total used free shared buffers cached Mem: 32086 24611 7475 0 0 24012 Low: 464 407 57 High: 31621 24204 7417 -/+ buffers/cache: 598 31487 Swap: 2047 0 2047

• NTFS write speed really slow (<15MB/s)

  - by Zulakis

  I got a new Seagate 4TB harddrive formatted with ntfs using parted /dev/sda > mklabel gpt > mkpart pri 1 -1 mkfs.ntfs /dev/sda1 When copying files or testing writespeed with dd, the max writespeed I can get is about 12MB/s. The harddrive should be capable of atleast 100MB/s. top shows high cpu usage for the mount.ntfs process. The system has a AMD dualcore. This is the output of parted /dev/sda unit s print: Model: ATA ST4000DM000-1F21 (scsi) Disk /dev/sda: 7814037168s Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 2048s 7814035455s 7814033408s pri The used kernel is 3.5.0-23-generic.

How can I fix the writespeed?

• Open Source Visualization and Dashboard Software

  - by helios

  I am working on an open source Application Performance Monitoring (APM) software and looking for a visualization tool with dashboard capabilities. I came across Graphite which looks pretty good but wondering if there is anything better out there before I settle down with that tool. Here's the list of features I am interested in: Must-Have Open Source license API to submit real time data Web-based visualization interface Persistence - file or database Nice-To-Have Dashboard Capabilities: Allow users to select a few metrics (CPU, Heap Usage, # of Active Users etc.) and place them on a single page for easier monitoring. Any suggestions?

• RewriteRule in htaccess in subdirectory

  - by Jay

  Windows server, running Apache. In my Apache conf, I have AllowOverride None for the root of a site and then I have a subdirectory set to AllowOverride All: <Directory /> AllowOverride None </Directory> <Directory "/safe/"> AllowOverride All </Directory> However, when I try to set up a rewrite rule in the subdirectory's htaccess file, nothing happens, I just get a 404 page not found error. Example: RewriteEngine On RewriteRule (.*) /blah?test=$1 [R=302,NC,NE,L] Rwewriting URLs are working fine from the root via the Apache conf. I don't understand why the rule is ignored. I don't want to do the URL re-writing within the conf because for this case I may need to be changing the redirects constantly and don't want to reload the server every time a change is made. I also don't want to affect server performance by enabling htaccess files site-wide, just in the subdirectory I need it.

• Debian, CentOS, Slackware, FreeBSD, OpenSolaris and Ubuntu Server Edition: Which one to use for an http web server?

  - by Ako

  I am going to install and administrate a virtual server for a small university. The server should run inside a virtual machine (VirtualBox OSE). It is only used in the university network and is invisible to the outside world. It should run Apache web server for PHP, MySQL and probably a mail server. I don't know which OS to use. Main criteria for choosing include ease of administration and updating, package management and performance. I wonder if anyone has any suggestions? And candidate OSs are: Debian, Ubuntu, CentOS, Slackware, FreeBSD, OpenSolaris. Add any other OS if you know any better alternatives.

• What are my X client options for MS Windows?

  - by Nick Bolton

  I need to connect to a headless X Windows server (running on Ubuntu) from my MS Windows 7 computer over a 100 Mbit network. I could use VNC (or any other remote viewer) but the 3D graphics performance would be lousy I imagine. I used to have it hooked up to a monitor, but that's broken now and I can't afford a new one. A friend advised that I could try and use an X client, and that the 3D graphics wont suffer too much over 100 Mbit. Cygwin seems to be an option, but I was wondering if there were any more lightweight options.

• Tools to automate recording streaming radio

  - by Stan

  Are there any tools that can automate recording online streaming radio? I've been using Total Recorder which has the following useful features: Handy scheduler Supports creating recording templates, so I can customize some high/low quality recording Unfortunately it requires opening the streaming radio in a browser and can't have another sound source at the same time; it's recording what comes out from the speaker. What I am looking for is given an online radio URL, the tool should be able to record the audio stream, no matter if I am playing any other music or not. Does such a tool exist?

• Dell PowerEdge 6850 Degraded HDD

  - by Matt

  Good Morning, We have a dell power edge 6850 with a degraded drive in the RAID array. I have never had to recover such an issue, so any help or advice would be welcome. Basically it hasn't affected the server at an operating system level, but has slowed down performance, I have a replacement drive in hand but as this is our main database server I want to proceed with extreme caution. My options as I see them are - Can I just hot swap the degraded drive with the new one and the data will automatically re-sync and we are all back to normal presumably this is dependant on the current raid configuration? reading various comments on-line I may need to re-configure the RAID array and re-build the broken drive? This screams disaster to me with the main worry being that I wipe any other data. Option 1 would of course make my day. Thanks in advance

• Video problem with Windows 7 Games

  - by Jordan 1GT

  I have a Dell xps M1330 which originally ran Vista, but I upgraded to Windows 7. When I try to run a Win 7 game like spider solitaire I receive the following message: "The game is running in software rendering mode. Hardware acceleration is either disabled or not supported by your video card driver which could slow down game performance. Make sure you have the latest video card driver installed and that hardware acceleration is turned on." I confirmed that hardware acceleration is turned on. When I go to Dell's site, I'm told there is no later video driver. When I run the game it runs very choppy. I wouldn't care, but I loaded a .pptx file which is doing strange things in normal view and I suspect may be related to the same video problem. Any ideas?

• BES 5.0 and MAPI calls to exchange system

  - by nysingh

  We have been using BES 4.1(5) for a while now and it has been a resource hog on exchange due to high number of MAPI calls. I have heard that BES 5.0 is even worse. the comparison i heard is that BES 4.1 is makes MAPI calls equal to 5 outlook clients per BB user and BES 5.0 makes MAPI calls equal to 10 outlook clients per BB user. can someone confirm if it is true? is BES 5.0 is really that bad in MAPI calls and for exchange performance. ? thanks

• shut down FTP from IIS 6 after <X> failed login attempts

  - by Justin C

  Is there a setting in IIS 6 to turn an FTP site off after a specified number of failed login attempts? It has already been documented on this site that a Windows server sitting on a static IP address can record tens of thousands of failed login attempts a month. One server I maintain has had tens of thousands of attempts made against the FTP port. I have solid passwords in place, so I am not overly concerned. I rarely have to use the FTP, so for the most part I turn it on and off as I need it. Sometimes though I forget to turn it off when I am done, only to find the next day that my EventLog is full of audit failures. I would want to set a high number, in case I just messed up the password. Something like if 50 failed login attempts happen, just turn off the FTP site. Then if I need it later I can just start it again.

• misaligned raid partition in Ubuntu 10.04

  - by Linux Jedi

  I attached two identical hard drives to my linux machine. Then using gparted I formated the first 1024 mb at the beginning of each drive as linux swap space. Then I went into system-administration-disk utility. In there I went to file-create-RAID array. I selected the remaining space in each of the two identical hard drives and created a striped raid array. After the array was created, a warning message appeared. It said "The partition is misaligned by 522240 bytes. This may result in very poor performance. Repartitioning is suggested." What do I do now? As far as I can tell, the partitions are identical.

• apache - subdomains are slower?

  - by matthewsteiner

  Using apache benchmark, I ran the exact same php application at my root domain and a subdomain. Even with multiple tests and high request numbers, the requests per second perform extremely differently. I mean something like this: example.com - 1200 requests per second bench.example.com - 50 requests per second What could be affecting this? These aren't using databases or anything, just mainly getting a simple page displaying. But it's the same app for both of them, and I'm wondering why they perform so differently. Ideas?
