PostDeferredCalls stop working a few hours after the

I have an application that communicates to multiple devices via individual threads that run essentially as while loops (1). Each thread will run periodic readings for it's device while the Scriptures are processed asynchronously via PostDeferredCallToThread() given that the Scriptures are generally generated from a separate thread. There is also a sign that is updated to the main thread via a call to PostDeferredCall. The program works well because around 2,5 hours, but then all the deferred post calls stop working. I've run in the two version and version with no difference in behavior of debugging. The functions PostDeferredCall * () are called, but target the function referencing the call is not.

How are deferred post calls queue and it is possible to overflow the queue? I am at a loss on how to solve it. I searched through the forums and couldn't find anything related. Can anyone offer some suggestions on what I can do to try to understand what is happening? Thanks in advance.

PS - I'm under CVI 2009 on XP pro

I have cparker,

I never noticed a similar behavior even in that I developed and applications that make heavy use of PostDeferredCall to pass information between threads. I don't know the size of the queues for postponed events, but they can indeed overflow as shown in this ancient knowledge base entry: Nevertheless, this causes an error to raise this rating shoud you, unless you have hidden all the warnings of error and the error is not fatal (and more, I can imagine the queue is not so limited in space) (: I am sure that the situation described in this knockout only fires due to a continuous display of messages in the queue, a situation which, in normal situations, should not met).

I had problems in the past when using deferred calls, but each time I ended up finding another mistake that caused abuse: leaks memory, concurrent access to variables or the ports series or so...

Are you sure all deferred calls are to honor until the system unresponsive? Could you have a gradual accumulation of calls unmanaged because of the very different calendar of reminders (very common PostDeferredCall as well as slower handling of deferred calls)? You have an error function in your verification code? Are you getting errors? What is the rate of PostDeferredCall offers? You can find the time spent managing the deferred calls and compare it with the the rate?

  • Receive the error "Windows Media Center Receiver Service stopped working and was closed" after the video card replaced

    I have a HP computer with Windows Vista Home Premium (32-bit) Service Pack 2.  He has a VISX PureTV tuner card and already had an NVidia GeForce 8400 graphics card.  This Setup has worked well for 2.5 years until what the graphics card died last week.  It has been replaced with an ATI Radeon HD3450 and both all Windows updates have made current.  Since that time, the TV tuner did not work.

    When you sign in to an account, it gives the error message "Windows Media Center Receiver Service stopped working and was closed".  I can use Media Center to watch the recorded video before, but if I try to watch live TV he hangs up and close Media Center.  If I try to configure the TV connection in Media Center it tells me that there is no tuner card.

    I looked at the map and see no problem and I tried it back in place.  He has the most up to date drivers (so does the new Radeon graphics btw).  I tried "Uninstall" in the Manager of devices and then put it back, but it was not good.

    "Windows Media Center Receiver Service Stopped Working and was closed" I tried all the fixes I've seen this error.

    I tried all the things I saw here and elsewhere related to this issue.  I did a "clean boot" with all non-Windows services and the disabled startup process.  He always did the same thing and gave the same mistakes.  It seems to be linked to a Windows service, and I hesitate to begin deactivation to track down.

    I ran 'sfc' in mode 'cmd' and he found no problem and none of the files to be fixed or could not fix.

    In the list of services, I changed the login for "Windows Media Center Receiver Service" to "Local System account", Local Service, Network Service and individual accounts, but no permits.

    I'm afraid I'm at the point of having to reload the Vista, but I don't know how to do this and want to avoid at all costs.  I don't have the recovery disks and software.  Is this enough?  Can I reinstall from the recovery disks without wiping everything aft of the configuratiion with which it was delivered?  I guess personal files will be OK (although I don't know this for sure), but I'm afraid I'll have to reinstall other applications, my family has developed over time and perhaps lose the media protected by DRM licenses.

    Someone has encountered anything like this or have any suggestions?

    Well, I finally stumbled into the solution.  It was caused by a conflict with another application.

    A few weeks before the card failure I had installed a program called video capture Replay Video Capture that I had bought a few months ago and never used.  However, at this time where everything including the TV tuner and Media Center worked well that's why I associate the problem with this software.  The problem comes after the system is rebooted the first time after installation.  In my case, it has not been rebooted until a few weeks later as part of the recovery of the fault of the graphics card.  Suddenly, the TV tuner did not work and I get the error messages mentioned in this title of the thread.

    I was at the end of my rope with this and was just to clean your system to do a reformat and reinstallation.  I uninstalled the Replay Videa Capture program to move it to another computer, and when you restart the computer I noticed that the error message disappeared.  Of course I went to the Media Center and could set up my TV tuner card and watch television.

    Looking for some info on this conflict, I found the following. (http://forum.applian.com//showthread.php?847-Conflicts-between-RVC-and-XP-Media-Center-OS&s=c0aec9897b51d550c47b919e73e59bfc)  It is difficult to say who is at fault in the present.  I'm sure that Microsoft accuses Applian for the encoder to mpeg (mcm2ve.ax) used in Replay Video Capture, while Applian says that the problem is a Windows process (ehrec.exe) that works all the time, hogging the tuner on the system device.  According to Applian other products similar to theirs have this conflict as well due to the process of Windows.

    Fortunately, there is a solution in this case.  Applian has released a new version of Replay Video Capture (version 4.2) that uses a different mpeg encoder and eliminates the problem.  Given the surprising lack of info about it on the Microsoft Web site, I wonder how many other people with this unresolved issue dealing with the same thing as me.  If you're like me and you don't usually need to reboot your PC for a few weeks at a time, you may never know to associate the problem with the application.  What a waste countless hours trying to diagnose, and most disconcerting, that's what I was about to go through a reformat and reinstall because of this.

    Thought I'd post here my problem resolution in the hope that it might help someone else.

    Note:
    Fixit would attempt to recover bad sectors on the hard disk, in the course of this process there are chances of data loss from that particular area.

  • Satellite Pro P300 restarts a few minutes after the stop

    Hello

    I'm unable to download the update of the BIOS for a Toshiba Satellite Pro P300 PSPCDE (WIN 3.00), the reason being that I wonder a user name and password to download the file!

    The laptop has this annoying problem to revive a few minutes after the laptop has stopped, and that's why I want to update the BIOS to see if it suits him. Laptop is running XP Pro (downgraded from Vista).

    Ideas how I can get the update of the BIOS and will it solve the strange rebooting problem?

    Paul

    Where are you trying to download the BIOS?
    I always download my updates on the official website of Toshiba and if it doesn't work maybe you should wait a day.

    To be honest, I doubt that the BIOS update will solve this problem. I often read about this problem and you can solve if you disable the wake on LAN function in the BIOS and Windows (properties of the wireless network card).

    Vista and Windows 7 updated drivers love then here's how update the most important.

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded:

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
    For each driver in the list, additional useful information is displayed: load address of the driver,
    Description, version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - device - Graphics Manager - note the brand and complete model
    your video card - double - tab of the driver - write version information. Now, click on update
    Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
    Uninstall - REBOOT it will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
    with their own software and drivers and all other main drivers that you have.

    Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
    Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
    BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
    each installation.

    Always check in the Device Manager - drivers tab to be sure the version you actually install
    presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
    in particular that) so to install a driver - reboot - check that it is installed and repeat as
    necessary.

    Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
    manually by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    http://Windows.Microsoft.com/en-us/Windows-Vista/disable-antivirus-software
     
    Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

    Step 2:

    Test the issue in a clean boot State, and check if the problem persists.

    Note: Follow step 7 to your computer as usual.

    Step 3:

    If the problem occurred recently, I do System Restore to the point that your computer was working normally.

    Hello

    It seems that the module defective sdb4mdu.dll is the cause of the crash. According to my research, sdb4mdu.dll is a driver printer interface module - which means that it is related to your printer drivers. Assuming that this module belongs to your default printer (which it might not, it is hard to say), disable it would risk instability. I recommend you to run the System File Checker. See this article: http://support.microsoft.com/kb/929833/en-us

    Don't forget to restart your computer after you run it.

    If this does not work, try to uninstall and reinstall the drivers for your printer.

    If it does not either, we can try to turn off the TPM. (first of all, creating a restore point in case something goes wrong)
