  • Slow performance on VMWare Linux server after Tomcat install

    - by Loftx
    We have a VMWare ESXi 4.1 server hosting a number of Linux and Windows guests. Recently a new Linux guest was added to this server and seemed to be performing well. Tomcat and some other applications on this server were then installed which seem to have caused the server to run really slowly without any obvious resource issues. Slow performance include: The time taken to bring up the password prompt over ssh takes a few seconds when it was previously instantaneous. The time taken to unzip a zip file which was previously a few seconds now takes around 30 seconds The time taken to compile vmware tools has increased by similar factors Both the VMWare console and monitoring commands don't report any issues with high CPU or memory usage but something is obviously slowing the server down somehow. Does anyone have any ideas what may be causing this issue and how it can be resolved? Thanks, Tom Edit As per your questions I’ve looked at some of the performance indicators on both the VM host and VM guest indicated. Firstly I tried reserving the full amount of memory (3gb) for this VM – no other machines on this server have any memory reservation. The swap in rate and swap out rate for the VM host and guest are now both zero. Balloon memory on the guest is zero and on the host is 3.5gb (total memory on the host is 12gb) The swap rate for the guest is also zero. Swap used by the host is 200mb on average. Compression and decompression rates for the host and guest are zero. Command aborts for the host are zero. Read latency is very low – maximum 10ms average 0.8ms. Write latency is higher – a few spikes to 170ms but mostly around 25ms – is this bad? Queue command latency is zero . Physical disk read latency averages 5ms but often 10ms Physical disk write latency averages 15ms but is often 20ms I hope this helps - let me know if you need any more information.

  • df -h showing wrong output in GB

    - by Anurag Uniyal
    If I list df output for KB, MB and GB, they do not match e.g. $ df -k |grep xvdb /dev/xvdb1 12796048 732812 11413172 7% /xxx $ df -m |grep xvdb /dev/xvdb1 12497 716 11146 7% /xxx $ df -h |grep xvdb /dev/xvdb1 13G 716M 11G 7% /xxx 12796048 KB = 12496.14 MB so that is slight off but OK 12796048 KB = 12.2 GB, 12407 MB is also 12.2 GB so why df is showing 13 GB or am I missing something?

  • How seriously should I take ECC correctable error warnings?

    - by David Mackintosh
    I have a pile of Sun X2200-M2 servers. These servers have ECC memory. In some of these servers, I am getting warnings in the eLOM about "correctable ECC errors detected", eg: # ssh regress11 ipmitool sel elist 1 | 05/20/2010 | 14:20:27 | Memory CPU0 DIMM2 | Correctable ECC | Asserted 2 | 05/20/2010 | 14:33:47 | Memory CPU0 DIMM2 | Correctable ECC | Asserted ...some more frequently than others. The kernel on this particular system is throwing EDAC errors as well, although with far more frequency than the eLOM is recording ECC events: EDAC k8 MC0: general bus error: participating processor(local node response), time-out(no timeout) memory transaction type(generic read), mem or i/o(mem access), cache level(generic) MC0: CE page 0x42a194, offset 0x60, grain 8, syndrome 0xf654, row 4, channel 1, label "": k8_edac MC0: CE - no information available: k8_edac Error Overflow set EDAC k8 MC0: extended error code: ECC chipkill x4 error EDAC k8 MC0: general bus error: participating processor(local node response), time-out(no timeout) memory transaction type(generic read), mem or i/o(mem access), cache level(generic) MC0: CE page 0x48cb94, offset 0x10, grain 8, syndrome 0xf654, row 5, channel 1, label "": k8_edac MC0: CE - no information available: k8_edac Error Overflow set EDAC k8 MC0: extended error code: ECC chipkill x4 error Now if the server is detecting Uncorrectable ECC, the system resets, so clearly that's bad and removing/replacing the identified stick or pair corrects the issue. But I am thinking that if the error is Correctable, then there's no immediate issue -- I can treat this as a warning and be prepared to pull the stick/pair if an uncorrectable error starts occurring?

  • 2008 Sever Randomly reboots.

    - by Jeff
    I'm out of ideas here. We have a 2008 Server that keeps rebooting 2-3 times a day at completely random times with an "Unexpected Shutdown" event. There are no Dumps, no events leading to it just like it loses power then comes back online. I ran a Diagnostic of the power supply and it has had continuous power for months. In addition, the temperature of the processors are maxing out at 40 degrees Celsius. Anyone have any ideas how to figure out why this is restarting all the time? This is a DMZed Web server so it doesn't do too much process wise. Here are the specs: Host Name: ~~~ OS Name: Microsoft Windows Server 2008 R2 Standard OS Version: 6.1.7600 N/A Build 7600 OS Manufacturer: Microsoft Corporation OS Configuration: Standalone Server OS Build Type: Multiprocessor Free Registered Owner: Windows User Registered Organization: Product ID: ~~~ Original Install Date: 5/27/2010, 4:25:47 PM System Boot Time: 2/14/2011, 5:35:01 PM System Manufacturer: HP System Model: ProLiant DL380 G6 System Type: x64-based PC Processor(s): 1 Processor(s) Installed.

  • How to convert a raw disk image to a copy-on-write image based on another image for use with kvm and

    - by Jean-Paul Calderone
    I have a virtual Windows machine running on kvm. Presently it has a 90GB raw disk image. I would like to clone this VM without having to keep two copies of the 90GB raw disk image around. It seems like a good approach for doing this is to make two new qcow or qcow2 images based on the original. First I converted the raw image to a qcow2 image: qemu-img convert -O qcow2 basewindowsxp.img basewindowsxp.qcow2 Then I tried creating a new image backed by this: qemu-img create -F qcow2 -f qcow2 -b `pwd`/basewindowsxp.qcow2 windowsxp-1.qcow2 Then I used virt-manager to point the original VM at windowsxp-1.qcow2. However, when I try to start up the VM in this new configuration, virt-manager reports an error: Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/engine.py", line 588, in run_domain vm.startup() File "/usr/share/virt-manager/virtManager/domain.py", line 150, in startup self._backend.create() File "/usr/lib/python2.6/dist-packages/libvirt.py", line 300, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: internal error unable to start guest: qemu: could not open disk image /var/lib/libvirt/images/windowsxp-1.qcow2 The error suggests that the filename was misspecified or that the filesystem permissions are too restrictive, but neither of these is the case: $ ls -l /var/lib/libvirt/images/windowsxp-1.qcow2 -rwxrwxrwx 1 root root 262144 2010-05-27 08:32 /var/lib/libvirt/images/windowsxp-1.qcow2 Why won't virt-manager start this vm?

  • Installing Mod-wsgi 3.3 for apache 2.2 and python 3.2

    - by aaronasterling
    I am attempting to install Mod-wsgi 3.3 on an ubuntu 11.10 desktop edition with apache 2.2 and python 3.2 I downloaded the source tarball and extracted it. I configured it using the --with-python=/usr/bin/python3 option to configure. This is the only copy of python3 that I have installed. I then issued the commands make and sudo make install. I attempted to restart apache using sudo /etc/init.d/apache2 restart and get the following error message: apache2: Syntax error on line 203 of /etc/apache2/apache2.conf: Syntax error on line 1 of /etc/apache2/mods-enabled/wsgi.load: Cannot load /usr/lib/apache2/modules /mod_wsgi.so into server: /usr/lib/apache2/modules/mod_wsgi.so: undefined symbol: PyCObject_FromVoidPtr Action 'configtest' failed. The Apache error log may have more information. ...fail! The error logs only inform us that it's a segfault: ` I checked to make sure that it's linked against the right python library with ldd mod_wsgi.so and got the output linux-gate.so.1 => (0x00d66000) libpython3.2mu.so.1.0 => /usr/lib/libpython3.2mu.so.1.0 (0x0065b000) libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0x00a20000) libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0x00110000) libssl.so.1.0.0 => /lib/i386-linux-gnu/libssl.so.1.0.0 (0x0028c000) libcrypto.so.1.0.0 => /lib/i386-linux-gnu/libcrypto.so.1.0.0 (0x0044c000) libffi.so.6 => /usr/lib/i386-linux-gnu/libffi.so.6 (0x002d9000) libz.so.1 => /lib/i386-linux-gnu/libz.so.1 (0x00eb3000) libexpat.so.1 => /lib/i386-linux-gnu/libexpat.so.1 (0x00abe000) libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0x002e0000) libutil.so.1 => /lib/i386-linux-gnu/libutil.so.1 (0x00c47000) libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0x00e24000) /lib/ld-linux.so.2 (0x0042c000) It seems to be linking against the python3 library so I'm not sure what the issue is. I have read on another question that mod-python can present problems however it was never installed. I saw that the directive WSGIPythonHome can be used to point to the correct python version and created a directory /usr/bin/apache2-python/ with a link named python and python3(the name I passed to the configure script) to /usr/bin/python3 This results in the same error. So I'm pretty sure it's using the correct version of python. I am now at a loss. Thanks in advance for any help. update Using the version from the repository I get the following log when I attempt to request a page: [Wed Mar 21 13:21:11 2012] [notice] child pid 5567 exit signal Aborted (6) Fatal Python error: Py_Initialize: Unable to get the locale encoding LookupError: no codec search functions registered: can't find encoding [Wed Mar 21 13:21:13 2012] [notice] child pid 5568 exit signal Aborted (6) Fatal Python error: Py_Initialize: Unable to get the locale encoding LookupError: no codec search functions registered: can't find encoding [Wed Mar 21 13:21:14 2012] [notice] caught SIGTERM, shutting down If I comment out the instruction to load mod-wsgi, the page serves normally.

  • What's the difference between these Intel things?

    - by Coldblackice
    My head still spins with the various Intel "things" that may (or may not) need installing/configuring/yaddayadda'ing: Intel Rapid Storage Technology (is this driver? a software manager/package?), Intel Chipset (i.e., Intel INF Update Utility, Intel RST OROM, Intel RST driver, Intel Matrix Manager, etc. I think I have a basic understanding that the OROM is the low-level BIOS "driver", which communicates with the higher-level RST driver (in Windows). But what's the Chipset Installation software? What's the INF installation/update software? I'm confused as to what the other pieces are (or why there are so many to begin with). And as for a practical matter -- I'm wanting to upgrade my BIOS with a recent Intel OROM included, and then also update the Intel RST drivers in Windows -- BUT, as for the Windows side of things, I don't know what I should uninstall -- the Intel Chipset installer thing (through official uninstaller), Intel RST Manager, finding the individual Intel devices in Device Manager and right-clicking-uninstall/deleting, etc.

  • IBM Websphere MQ Server alternatives

    - by I Clark
    Are there any alternatives to IBM Websphere MQ Server for Windows? We need to access a remote Queue Manager that doesn't support client connections (only Queue Manager to Queue Manager). I've noticed that there are some BizTalk Host Integration adapters but they only seem to behave as clients (one transactional, the other non-transactional).

  • Performance monitoring on Linux/Unix

    - by ervingsb
    I run a few Windows servers and (Debian and Ubuntu) Linux and AIX servers. I would like to continously monitor performance on these systems in order to easily identify bottlenecks as well as to have an overview of the general activity on the servers. On Windows, I use Windows Performance Monitor (perfmon) for this. I set up these counters: For bottlenecks: Processor utilization : System\Processor Queue Length Memory utilization : Memory\Pages Input/Sec Disk Utilization : PhysicalDisk\Current Disk Queue Length\driveletter Network problems: Network Interface\Output Queue Length\nic name For general activity: Processor utilization : Processor\% Processor Time_Total Memory utilization : Process\Working Set_Total (or per specific process) Memory utilization : Memory\Available MBytes Disk Utilization : PhysicalDisk\Bytes/sec_Total (or per process) Network Utilization : Network Interface\Bytes Total/Sec\nic name (More information on the choice of these counters on: http://itcookbook.net/blog/windows-perfmon-top-ten-counters ) This works really well. It allows me to look in one place and identify most common bottlenecks. So my question is, how can I do something equivalent (or just very similar) on Linux servers? I have looked a bit on nmon (http://www.ibm.com/developerworks/aix/library/au-analyze_aix/) which is a free performance monitoring tool developed for AIX but also availble for Linux. However, I am not sure if nmon allows me to set up the above counters. Maybe it is because Linux and AIX does not allow monitoring these exact same measures. Is so, which ones should I choose and why? If nmon is not the tool to use for this, then what do you recommend?

  • FFMPEG Segfault Solutions

    - by Brentley_11
    I'm trying to convert a bunch of movies into h.264 mp4's using FFMPEG. These movies are sourced from various portable camcorders such as the Flip Mino HD and the Kodak ZI8. One issue I'm having with video from the ZI8 is it seems to be causing FFMPEG to segfault.

  • My HP-Vista based laptop has become very slow recently

    - by goldenmean
    My HP laptop which has Vista Home premium. When I try to start Firefox, internet explorer, it becomes very slow. No other app. When i checked the Performance in Task Manager. It shows the Physical memory , Free as 0 bytes, almost always. This has been recently. Earlier it didn't used to be zero. Laptop has 2GB of RAM. I have nothing running in my tray except - Sound control, Laptop power plan indicator,Network status indicator. There are no other processes whose memory usage adds up to so high to make Free memory as 0. Then what could be hogging the memory and make the laptop very slow. Any pointers would help as it is crawling at the moment.

  • Network shares do not mount

    - by Alex
    My network shares were mounting fine yesterday.. suddenly they are not. They were mounting fine for the last two weeks or however long since I added them. When I run sudo mount -a I get the following error: topsy@monolyth:~$ sudo mount -a mount error(12): Cannot allocate memory Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) mount error(12): Cannot allocate memory Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) mount error(12): Cannot allocate memory Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) mount error(12): Cannot allocate memory Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) topsy@monolyth:~$ I followed this guide when setting them up: http://ubuntuforums.org/showthread.php?t=288534 So I tried removing them by doing the reverse, and then rebooting, then adding them again and rebooting. Problem persists.

  • FFMPEG Segfault Solutions

    I'm trying to convert a bunch of movies into h.264 mp4's using FFMPEG. These movies are sourced from various portable camcorders such as the Flip Mino HD and the Kodak ZI8.

  • Windows Server 2008: Terminal Services / VDI

    - by JohnyD
    I have a Dell R710 with 72GB of memory running Hyper-V. Within Hyper-V I have a Windows 2008 (32-bit) VM running Terminal Services. How do I allocate memory so that any user who connects to this Terminal Server (from their thin-client) is allocated 2GB (or whatever amount I choose) of memory? Currently I have provisioned the TS with 2GB of memory but it seems that this is shared among all that connect. Please let me know if there is further information I can provide. Thank you. Update 1: What I'm looking to accomplish with this server is setting up a VDI to allow users to connect from thin-clients from within our network. They will also have to connect from outside our network via VPN which is already in place. Am I able to set this up using Windows Server 2008 (not R2) because I have a 16-bit application which needs to be supported. Unfortunately it's not a candidate as a Remote App.

  • why does my computer crash?

    - by chobo2
    Hi my computer keeps crashing and I don't know why. At first I thought because I had my cpu over clocked that it all of sudden was crashing. So I set my cpu back to regular speed. This did not help. I then thought it was because 2 sticks of my memory where from a computer that suffered from a power surge. However I just ran the windows memory diagnostic tool( extended) and after like 6 hours of testing my memory it found no errors. So now the only thing that is left is windows 7 64bit. I first over clocked my cpu for a couple months while running XP. Never had a problem. I installed the memory and windows 7 at the same time. But I not sure if it is my memory now since it passed the diagnostic tests. However I am not sure if it is windows 7 either has I installed it twice in the last year. I really don't want to go back to XP to find out if this is the case. So here are my blue screens of deaths(from bluescreen). https://sites.google.com/site/myerrorswin7/errors (I hope you enjoy my great site lol) As you can see most of them are different NTFS_FILE_SYSTEM KMODE_EXCEPTION_NOT_HANDLED BAD_POOL_HEADER IRQL_NOT_LESS_OR_EQUAL SYSTEM_THREAD_EXCEPTION_NOT_HANDLED SYSTEM_SERVICE_EXCEPTION

  • Is it possible to ensure that multiple applications run in the same terminal server session using RemoteApp?

    - by mbrownnyc
    We are interested in implementing RemoteApp on Windows 2008 R2 to serve out a few programs. Since the developers use shared memory to pass messages between processes, it is necessary that we provide them with a solution that will allow this. They have researched and discovered that if the applications exist in the same terminal server session that they will be able to access shared memory. Is there a way to absolutely ensure that multiple RemoteApps are running within the same session (with the same user) so that they can access the same shared memory?

  • How to change the amount of RAM displayed in System Properties

    - by Nicu Zecheru
    I have this product that requires at least 1 GB Physical Memory in order to be installed. On my XP Pro machine I have 1 GB of RAM but in System Properties only 0.99 GB of RAM is displayed. The problem is that the product installer checks the memory displayed in System Properties (just a guess, not sure) and cannot continue the setup because it sees only 0.99 GB. Is there any way to change the displayed memory in the System Properties? Or how can I trick the installer to skip the memory check? Thanks.

  • Need to upgrade DDR2 RAM on HP Desktop

    - by jds
    I have this HP Pavilion Desktop. As you can see, that page says the memory speed supported is PC2-4200. It currently has a 512 MB stick - CPU-Z Screenshots: hxxp://i41.tinypic.com/j5clj6.jpg and hxxp://i39.tinypic.com/20tldlc.jpg However, a crucial.com scan gives a slightly different report - hxxp://crucial.com/systemscanner/viewscanbyid.aspx?id=5718CFE831D926C3 It says the system can support PC2-5300 memory. So my question is which one should I trust? I want to upgrade the computer's ram to 2 GB (the maximum supported), because XP Media Center is giving me problems and I will install Windows 7 on this. PC2-6400 is the most common DDR2 memory I have been able to find here in the market. Will it cause any problems if I install 2 × 1 GB PC2-6400 DDR2 memory sticks (in dual channel) in this computer, (afaik, it will just run at the lower speed of 533 MHz, or whatever the motherboard supports), or do I absolutely need to get PC2-4200 sticks?

  • ASUS K55VM Laptop unexpectedly shuts down

    - by Abhishek Sha
    I've read quite a few questions on SuperUser of people having laptop shutdown problems but mine is different. My laptop specs: Intel Core i7 3610QM (IvyBridge) NVIDIA GT630M 2GB and Intel GMA4000 8GB RAM Windows 7 64 Bit My laptop occasionally shuts down when playing FarCry 3. It's around 5 months old. I've played games like Crysis and it never shuts down unexpectedly. Since I experienced this shut down recently, I decided for GPU-Z to log the temperatures. The final log value at the time of shutdown were thus: GPU Core Clock [MHz] - 797.3 GPU Memory Clock [MHz] - 896.8 GPU Temperature [°C] - 89.0 GPU Load [%] - 99 Memory Controller Load [%] - 36 Video Engine Load [%] - 0 Memory Usage (Dedicated) [MB] - 535 Memory Usage (Dynamic) [MB] - 53 VDDC [V] - 1.0620 My drivers are up-to-date and I didn't encounter any BSODs at the time of shut down. It simply turns off.

  • 2560 x 1600 screen resolution not available when a second monitor is attached.

    - by sgmoore
    I am running Windows 7 (64-bit edition) and have a 30" Dell 3007WFP monitor which runs at a screen resolution of 2560 x 1600. This works perfectly until I try to connect a second monitor, and then the screen resolution on the main monitor immediately drops to 1280x800 and I can't change it back up to the correct resolution until I disconnect the second monitor. The graphics card is a Nvidia Quadro FX 370. This has a dual link DVI connector (to which the 30" is connected) and a single link DVI connector. The second monitor can run at 1920x1080 and is connected using a VGA to DVI connector. Note, it does not seem to matter whether the second monitor is running at 1920x1080 or even at 800x600. Windows reports Total Available Graphics Memory: 3839MB Dedicated Video Memory: 256MB System Video Memory: 0MB Shared System Memory: 3583MB Does anyone know if this a limitation with the video card, memory, drivers, connectors or something else? If this is a limitation with the video card, can anyone recommend a PCI Express 16 card that would support at least this setup, but preferably support two 30" monitors both running 2560 x 1600. (I'm not into gaming etc, so it doesn't need to be very powerful)

  • Why does the java -Xmx not working?

    - by Zenofo
    In my Ubuntu 11.10 VPS, Before I run the jar file: # free -m total used free shared buffers cached Mem: 256 5 250 0 0 0 -/+ buffers/cache: 5 250 Swap: 0 0 0 Run a jar file that limited to maximum of 32M memory: java -Xms8m -Xmx32m -jar ./my.jar Now the memory state as follows: # free -m total used free shared buffers cached Mem: 256 155 100 0 0 0 -/+ buffers/cache: 155 100 Swap: 0 0 0 This jar occupied 150M memory. And I can't run any other java command: # java -version Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. # java -Xmx8m -version Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. I want to know why the -Xmx parameter does not take effect? How can I limit the jar file using the memory?
