Anyone seeing piles of ESENT (id 910) warnings in Application log?

    Question

  • These things have been happening since I installed W8CP a couple months ago. Most ESENT events are not warnings, such as:

    Description:
    msiexec (3996) Instance: The database engine attached a database (1, C:\ProgramData\Microsoft\Windows\AppRepository\PackageRepository.edb). (Time=0 seconds)

    However, every few days or so (sometimes spaced out by several days), there will be one of these happening every minute, sometimes for hours on end. I'm assuming that it pertains to the same AppRepository directory as seen above, though perhaps not the same file. Is this a bug, or is there something I can do?  Where is the maintenance task for this event (I looked in Task Scheduler, but don't see anything that I can tie to it).

    Log Name: Application
    Source: ESENT
    Date: 5/5/2012 11:56:47 AM
    Event ID: 910
    Task Category: Performance
    Level: Warning
    Keywords: Classic
    User: N/A
    Computer: Z68
    Description:

It has run 309390 times since maintenance was triggered.

  • Did you install any database or program that is using database?

    What program is that?

    Make sure to report all issues , if Windows asked you to send report and keep your PC update.

  • No, they're system databases. Everyone has them.

  • Just to follow up on what's present in RTM, you still see plenty of non-910 ESENTs, but very few 910 warnings. It averages one every two days so far, which is fine. Still no idea what it really means, though.

  • Just a quick update on Event ID: 910; Source: Esent;  Task Category: (7)

    I loaded win8 pro on the 30/10/12 at about 0230 did ms update at (1415) loading 2756872 and 2768703

    received first two 910 events at 1444, had none prior to the updates.

    Notice reference to taskhostex  in ms doc "File attributes tables for update 2756872.csv"

    I don't know whether this helps ?

  • I am experiencing random computer freezes and at least 2 times a day I see this error in Event Viewer .

    Using W8 Pro

    Monday, November 19, 2012 6:46 PM
  • I'm seeing this one as well.  It just started after I recently upgraded from Windows 7 (Pro, 64-bit) to Windows 8 (Pro, 64-bit).  And to make matters worse, today I had my first hard lock-up on this machine.  (That's what took me to the event logs.)
    Thursday, December 06, 2012 1:08 PM
  • Same problem here. Freezes actually a lot. I always can return to the start menu but you can't launch apps there during maybe a minute.

    I have Windows 8 Pro and did a clean install.

    Hope the problem will be quickly resolved in an update !

  • I am experiencing the same issue since installing win 8 pro.  Went into my logs 20 mins ago, as my desktop has been pretty much unusable for the two weeks and much to my dismay, I've got a pile of 910 errors.  Terrific.  My laptop is not going to cut it today either, I need some muscle...knew I should have dual booted.  Looking forward to seeing a resolution.

  • I have been having the same issue with ESENT 910 event on win8, system becomes unstable and some programs don't work properly, logging out and logging back in does not fix the problem, a restart does. However I have come across a temporary quick fix, kill the program with the instance ID that the event gives. My problem seems to be somewhere in svchost (netsvc), killing the process fixes the stability issues and everything works fine, until whatever triggers the problem happens again. I did not check which service is causing the error, will try to pin it down if it happens again.

    /edit

    After the error happened again and some further investigation, it seems like Windows Update Service is the problem. To fix it, go to control panel-troubleshooting and run Windows Update Repair, after the repair, remove the cached Windows Update files, you can do this by right-clicking on c: drive-properties-Disk Clean-up once it opens and scans the system, select Clean up system files, it will do another scan, select Windows Update Cache files and free the space, clean up the other unneeded files too. It looks like that fixes the problem.

  • Above, to clarify, by "run Windows Update Repair" are you meaning "install the latest updates from Microsoft" as compared to some mechanism to repair "Windows Update" itself?

    For others, in WinSvr 2012/2008, you may need to install the desktop experience package to enable disk cleanup. See: http://blogs.technet.com/b/chad/archive/2012/10/08/tip-51-cleanup-on-isle-3-get-back-disk-cleanup-wizard-on-windows-server-2008-amp-2012.aspx.

  • I'm getting the same ESENT Warning in Event Viewer every once in a while, usually between 1-3 days and only one single Warning:

    Windows 8 Pro x64 - Event ID 910 - ESENT

    svchost (1420) The database cache size maintenance task has taken 60 seconds without completing. This may result in severe performance degradation. Current cache size is 6 buffers above the configured cache limit (160 percent of target). Cache size maintenance evicted 1 buffers, made 35430 flush attempts, and successfully flushed 0 buffers. It has run 5989 times since maintenance was triggered.

    My system works perfectly fine, stable and performance is well on the hardware specifications but i'm really curious what this Warning means and why Microsoft has no KB article or fix for this.

    Regarding Windows Update: I have automatic updates disabled and only run a manual check once every week. I don't see any option "Windows Update Repair" or similar. I do run Disk Cleanup on a regular basis and removed old Windows Update Cache files a couple time.

    Kind Regards

  • Windows 8 .. Control Panel all items .. Troubleshooting .. has repair windows updates and an advanced link too, to run as administrator.

    Each and every time I run it.. it finds and repairs 'something?  Windows updates fine here regardless of the repair or not.

    And I keep getting ESENT event id 102, 103, 105, 326, 327 informationals.. mostly about like this;

    msiexec (1436) Instance: The database engine attached a database (1, C:\ProgramData\Microsoft\Windows\AppRepository\PackageRepository.edb). (Time=0 seconds)  

    Wish I knew what they are really.

  • Above, to clarify, by "run Windows Update Repair" are you meaning "install the latest updates from Microsoft" as compared to some mechanism to repair "Windows Update" itself?

    There is a troubleshooting section under Control Panel in Windows 8, that section contains "Fix problems with Windows Update". However I think that clearing the cache was more important in fixing my problem than the repair.

    Each and every time I run it.. it finds and repairs 'something?  Windows updates fine here regardless of the repair or not.

    And I keep getting ESENT event id 102, 103, 105, 326, 327 informationals.. mostly about like this;

    msiexec (1436) Instance: The database engine attached a database (1, C:\ProgramData\Microsoft\Windows\AppRepository\PackageRepository.edb). (Time=0 seconds)  

    "msiexec (1436)" is the windows installer process, you can probably trace the PID(1436) to some program installation, it might not be related to Windows Update. Try to clear the cache as I described in the previous post, you can always kill the process and see what triggers it, could be a corrupt installer.

  • cybercritic thanks.

    Did that .. updates repair and clean disk system,  no change.  Two or three hours later after Defender updated that I saw... I looked in the event logs. Still happening earlier from something else.  Try to chase it down by the time.  Lots to look at down the App & Services logs.  Got sidetracked with something else this time .. some app runs every minute and logs   hah.  kind of a waste of electronic paper and ink.

  • In my case the ESENT Event ID 910 warning's svchost.exe process is always pointing to the process/service ID of Windows Firewall.

    Can anyone confirm that on their system? I already tried Firewall specific things, resetting its settings to defaults, clearing logs etc. Does anyone know how to clear the Database Cache for Windows Firewall?

    Kind Regards

  • Got 2 ESENT 910 events yesterday, 7 hours apart, and one today, on Win 8 Pro 32-bit system.  All pointed to svchost (624) which in my case looks like:

    Service Host: Local Service (no Network)(4)

    •    Network Connected Devices Auto-Setup
    •    Windows Firewall
    •    Diagnostic Policy Service
    •    Base Filtering Engine

    Disk Cleanup did not find much stuff - I had already cleared out a bunch of left over files from Win 8 updates several days ago.

    Interesting that the times for these three events are 2:01:02pm, 9:01:01pm, 9:01:01am.  So maybe they are associated with a scheduled task?

    Looking at Task Scheduler, the only Active Tasks I see listed as scheduled hourly are three tasks labeled

    GoogleUpdateTaskUserS-1-xxxx-1001UA 

    GoogleUpdateTaskUserS-1-xxxx-1003UA  

    GoogleUpdateTaskUserS-1-xxxx-1000UA  

    The last of these is scheduled 2 minutes after the hour.  Can anyone else make this type of association?

    --------

    I've uninstalled Chrome & Sketchup.  I then deleted all Google tasks from Task Scheduler & rebooted.  During reboot I got messages that system was Configuring Windows Updates.  Will see what happens over next few days.

  • I just had a good week without new ESENT 910 errors in the Event Viewer and now one of them showed up again yesterday and 2 today. Its always the same 4 services involved you posted above. There are no problems with my system I can ignore this error but its still bugging me and I want to know whats causing it.

    Are Microsoft devs reading this forum or how can we forward this problem to get a fix?

    The normal Microsoft support is not quite cutting it with their standard copy/paste answers telling you to start Windows in clean-boot mode with non-MS services disabled (no offense).

    Kind Regards
