  I restored windows to State factory but still present memory leak.

  Memory leaks are a common error in programming.
  leak memory occurs when a computer program consumes memory, but is unable to release it in the operating system.

  In your case, it would be necessary to know what application or process that runs in the background do
  This can be very long process you would need to install a system of fees will need to check the memory leak after each installation of driver or another application

• Computer Vista becomes errors with physical memory dump blue screen and restart

  I have a problem with my computer going to a blue screen, dump physical memory saying and a lot of other things, then by restarting. It grows more and more frequent.
  Please help and thank you

  You have several errors:

  LeAPC_INDEX_MISMATCHErreur bug control has a value of 0x00000001. This indicates that there is an inconsistency in the index of State APC.

  PAGE_FAULT_IN_NONPAGED_AREA bug control has a value of 0 x 00000050. This indicates that invalid system memory was referenced.

  Control bug IRQL_NOT_LESS_OR_EQUAL 0x0000000A value a. This indicates that Microsoft Windows or a driver in mode accessed kernel memory paged at DISPATCH_LEVEL level or above.

  Bug SYSTEM_THREAD_EXCEPTION_NOT_HANDLED control has a value of 0x0000007E. This bug check indicates that a system thread threw an exception that the error handler did not.

  One of the mistakes led to the crash by aswsp.sys. The rest of modules of windows so other thing he led to the crash. So its best to start with aswsp.sys. This file is part of your avast antivirus software. I would download the latest avast antivirus. Uninstall the version you have and install the latest version. I'd also that you have the latest windows updates and patches. Once you've done that I could monitor and see if you have more blue screens.

• Difference between (minidump) and (memory.dmp)?

  Separated from this thread.

  is there a difference between (minidump) and (memory.dmp) I use windows 10

  The main difference is size. Memory dumps are larger and contain a bit more information.

  In most situations, it is best to configure the computer to produce a dump of memory the kernel in case of system failure. A complete memory dump is a very large file to manage so it is more convenient to work with kernel images of memory when you try to resolve the blue screen errors.

  I suggest that you change your dump file settings to produce an image kernel memory. Select the hotkey Win + X , Control Panel, system, advanced system settings, Advanced tab, and click the button settings to start recovery. Under system failure, select the checkboxes before to write an event to the system log and restart automatically. Change the option Write debugging information by using the scroll to the right for image kernel memory. Click OK , and in the next window, click apply and OK. Restart your computer to apply the changes.

• VMware Fusion 7 and VMware Tools - leak memory in Debian comments

  At some point during my updates from Mac OS X to Yosemite, VMware Fusion to 7.x and my Debian a guest to 8.0 "Jessie" on my 2012 Mackbook Pro, leaking memory of the Linux kernel is developed.  If I follow these steps, then I'd lose soon about 3 GB memory of the core area.

  1. Install Debian Jessie in a new machine virtual de VMware Fusion
  2. Install open-vm-tools or VMware Tools bundled.
  3. Perform an intensive IO as operation simply cat/dev/zero |-c 1000000000 head >/tmp/test.txt.
  4. Smem - wtk and see ~ 3 GB memory under the dynamics of the kernel memory, benefit.

  I opened the 15709682007 assistance request and the representative said that they will fix the problem in a future release. In the meantime, I have what seems to be a workaround for someone else that is affected.  Basically, pulling packages from backports jessie seems to have solved the problem.  This is based on the comments added to open-vm-tools.

  1. Add the Debian repository -backports jessie in /etc/apt/sources.list
  2. sudo apt - get update; sudo apt - get install t Jessie-backports open-vm-tools-dkms open-vm-Tools-Office
  3. sudo apt - get - t jessie-backports dist-upgrade (install kernel 4.1)
  4. Restart comments

  A few quick thoughts:

  1. If you have several virtual machines (or other programs) running on your computer host and VMware Fusion detects that there is memory pressure on your host computer, it uses the "balloon" (vmw_balloon for the latest distributions of Linux) Guest pilot to fly some memory of the guest OS.  This memory "stolen" would appear as memory Dynamics non-cache kernel inside the guest.  Running "sudo rmmod vmw_balloon" should release all memory climbed to the guest OS.  Note that using the balloon driver generally improves the performance of the guest and host, despite the appearance of fear "used memory" inside the guest-"used memory" is just a thing of accounting that we had to use in order to change the priority of the memory between the host and the guest.  It is not "used" in the conventional sense of the term.

  2. I believe that recent versions of virtual hardware non-cache dynamic kernel allocate the necessary memory for SVGA and 3D features (display RAM, texture RAM, etc.).  Disable graphic 3D acceleration or by reducing the amount of graphics shared memory if you are using a new version of virtual hardware (both in the VM > settings... > display) might help.  Decommissioning of a virtual equipment as early (in the VM > settings... > compatibility) can also help.

  See you soon,.

• Setting the shared memory size linux

  Hello
  I'm a bit confused on the parameters of the kernel, can you please share your views on this one please.
  Shared for the tt in the linux kernel memory is calculated as follows:
  Shared mem = perm size size temp + journal + fresh size generals 7 MB
  
  but when I look at the linux sysctl.conf, I saw that there is a great value for sharing memory setting (default) as ~ 68 GB, then I think that I should not override/decrease this value. What is your opinion? Setting the value default (68 GB) helps my DB behave badly? Or by assigning the value calculated as in the equation makes them much faster?
  
  # Control the maximum shared segment size, in bytes
  kernel.shmmax = 68719476736
  kernel.SEM = 250 32000 100 100
  
  # Control the maximum number of shared memory pages segments
  kernel.shmall = 4294967296
  
  Thank you very much.

  The shmmax kernel parameter simply sets a limit on the maximum size of a shared memory segment individual. It has no direct effect on performance. In general, it should be set large enough to allow the largest shared memory segment you need to create but smaller then the amount of physical memory in the machine. Shmall parameter sets a limit of large system on the total amount of shared memory (all active segments added) can be allocated. It must be also, in General, lower then the [physical memory on the computer.

  If one is defined on more memory in the machine is not an immediate problem. However, in this case, it is possible to create shared memory that is larger than the physical memory of the system (as far as adequate swap space is configured), and if this happens then the overall performance of the system will be affected, probably seriously.

  Thus, work on what you need and set accordingly.

  Hello

  HP have a few useful pages for their servers, I keep these around as reference, they are called Quickspecs... lists lots of interesting information about the server and its components..., it's the quickspec for the DL360 G5 it seems only the fully buffered collection list... so you may be stuck with requiring that...

  Thank you for using communities of Apple support, Deirdre-2D!

  It seems that you encounter several different questions since Wednesday last on your Mac Pro. Let's see if we can get these cleared up for you. Test questions you mentioned having tried every troubleshooting step. Don't hesitate to jump steps you have already tried, but let me know?

  1. your Mac hard drive backup - before you start troubleshooting procedures, I always recommend a fresh backup. It is preferable "to have" one the "need."

  2 try safe mode if your Mac does not start -even if your Mac starts, which makes sure it starts successfully.

  3. How to test one question in another user on your Mac account - this will help determine if the questions are found in all your user account or if they are systemic.

  4. on the recovery of OS X - if you're still with these problems, reinstall the operating system on your Mac.

  Have a great day!

• NIDAQ800_RedHat.ISO DAQmxSet / GetBufInputBufSize)

  Hello.

  It helps for the first time.

  The program of the module S series HAVE as PXI-6133 is developed using the version of the C/C++ API of Linux DAQmx8.0.
  (NIDAQ800_RedHat.iso)

  It occurs in the place where the task is made to commit by the DAQmxTaskContol of-50352 function.

  The BufInputBufSize seem to influence whether we look at it.

  PXI-6133 is a mistake in a case when making it to 5 400 000 with OK when you're 5 300 000.

  PXI-6133 is a mistake in both cases, when making it to 2 800 000 with OK when you're 2 700 000.

  PXI-6133 is a mistake in three cases by making 1 900 000 with OK when you're 1 800 000.

  To achieve a multi channel (about 40) and sampling at high speed (up to 1 ms/s), the BufInputBufSize is flexible specified.
  (MXI - 4 was the execution of 78Mbyte/s transfer MXI-Express has the execution of transfer of 110Mbyte/Sec.)

  I want to do.

  BufInputBufSize has been studied in the DAQmx8.7.2 of Windows version.

  When using two PXI-6133, 8 000 000 could be defined.

  The limitation of the Linux version very much hope for improvement, because the patch is acceptable if it is a problem with DAQmx.

  Please teach if there is an action method if it is a nucleus and a problem with LinuxOS.

  Best regards, I hope.

  Sorry for the delay to return to you.  I've been a bit busy with a number of other things.  I was talking with a colleague the other day and he had a recommendation that could help.  NOR-DAQmx 8 for Linux uses apparently vmalloc to allocate kernel memory buffers.  However, the vmalloc space is only 128 MB on systems with more than 896 MB of space.  I have not had the chance to try this out, but you can increase the amount of vmalloc space by adding "vmalloc = 512M" to your kernel in grub boot line.  The upper limit to vmalloc space is< 1="" gb. ="" since="" it="" sounds="" like="" you="" have="" plenty="" of="" ram="" it="" seems="" like="" a="" reasonable="" way="" to="">

• How to check the use of the ram?

  I have 3 GB of ram on my pc, and I want to know how to check the use of the ram in xp pro? is the use of FP in taskmanager? or (k) of the kernel memory?

  I have 3 GB of ram on my pc, and I want to know how to check the use of the ram in xp pro? is the use of FP in taskmanager? or (k) of the kernel memory?

  Yes, Yes... and no. All applications on your computer uses RAM, not only the pagefile or system (kernel).

  What are you really trying to do?

  To help you, we will need for the. DMP files to analyze what exactly happened at the time of the accident, etc.

  If you do not know where. The DMP files, here's how to get to them are:

  1. go to the folder % systemroot%\Minidump.

  -% SystemRoot % is the environment variable for your Windows directory. For example, C:\Windows.

  2 copy everything. DMP files in the Minidump on your desktop folder, create a new folder on the desktop for these. DMP files and then the zip folder. You can then either use a 3rd party tool such as 7-Zip/Winrar, or you can use the default method of Windows of zipping of folders.

  Compress and uncompress files (zip files).

  Please note that all programs "cleaner" such as TuneUpUtilities, CCleaner, etc., default will remove. DMP files after use. That said, if you have run these software and your Minidump folder is empty, you must enable the system to crash once more to generate a crash dump.

  3. download the. ZIP containing the. Files DMP Onedrive or a Web hosting of your choice and paste it in your answer.

  Favorite sites: Onedrive, Mediafire, Dropbox, etc.. Nothing to do with the timers waiting, download managers, etc.

  4 (optional): The type of. DMP files in the Minidump folder are known as small images of memory. In any % there will be what we call a kernel memory dump (if your system is configured to generate). It is labeled MEMORY. DMP. The difference between small memory images and images of memory the kernel in the simplest definition is that a dump memory kernel contains much more information at the time of the accident, which further debugging of your question. If your upload speed and you're not going against any strict caps bandwidth and/or use, etc., of the kernel memory Dump is the best choice. Note that images of the kernel memory are much larger in size due to containing much more information, that's why I mentioned the download speed, etc..

  If you plan to use Onedrive but don't know how to download it, please see the following:

  Download pictures and files to Onedrive.

  After doing this, to learn how to share the link to the file if you are not aware, please visit the following link - share files and folders and change the permissions and view 'Get link'.

  If your computer does. DMP files, follow these steps:

  1. start > type systemroot which should show the Windows folder, click it. Once inside this folder, make sure there is a Minidump folder created. If not, CTRL-SHIFT-N to create a new folder and name it Minidump.

  2 Windows key + Pause key. This should appear in the system. Click Advanced on the left system settings > advanced > performance > settings > advanced > make sure there is a check mark for "manage automatically the size of pagefile for all readers."

  3 Windows key + Pause key. This should appear in the system. Click Advanced on the left system settings > advanced > startup and Recovery > settings > system > ensure there is a check mark next to "write an event to the system log.

  Make sure Small Memory Dump is selected and ensure that the path is % systemroot%\Minidump.

  4. ensure that viewers is ENABLED:

  Start > Search > type services.msc > on the name tab, search for Windows Error Reporting Service > if the service status is not started, then right-click and select start. Also to ensure that, under Startup Type set to automatic rather than manual. You can do this by right click, select properties and under general selection on 'Automatic' startup type and then click on apply.

  If you can not get into normal mode to do this, please do so via Safe Mode.
