MOSS - Common Issue - events 7076, 6398, 6482 listed in the Event log and/or IIS MMC not responding

We had a big number of cases where customers reported the following pattern:

Event ID 7076 -

Office SharePoint Server "Attempted to read or write protected memory. This is 
often an indication that other memory is corrupt. " 
"System.AccessViolationException: Attempted to read or write protected memory. This 
is often an indication that other memory is corrupt.
...

Event ID 6398 - 

Windows SharePoint Services 3 NERA-WPWFE1 
"Microsoft.Office.Server.Administration.ApplicationServerAdministrationServiceJob 
""cddd50c5-bf98-4496-85b5-d1c755e4dca7 " 
"Exception from HRESULT: 0x80005006  
 
Event ID 6482 -
 
"Microsoft.Office.Excel.Server.ExcelServerSharedWebServiceInstance 
""3ff29932-af40-4296-b012-eb71dee2c40e ""Attempted to read or write protected 
memory. This is often an indication that other memory is corrupt. "" 
System.AccessViolationException: Attempted to read or write protected memory. This 
is often an indication that other memory is corrupt. 

Some customers also reported that the IIS MMC stops responding and a restart of IIS is required to resolve the problem.

After some research we found that all these problems were caused by a problem in the IIS ADSI providers. A hotfix to resolve this issue is meanwhile available:

946517 - FIX: You may be unable to manage IIS 6.0 by using Server Manager if two threads access IIS 6.0 at the same time

  • Nice Stefan,

    I never put the events together with the IIS going belly up and after running an IIS Reset it always came up clean and stayed clean for a while then would happen after a few months.  Great post.

  • I am getting a 6398 error in the event viewer. I am trying to mail enable a document library. When i do this within sharepoint it tells me error in application. Then when I look in event viewer under application, it gives me the 6398 error repeatedly.

    Can you help?

  • Hi Jeremy,

    please ensure to install the following things:

    - Windows Server 2003 SP2

    - IIS FIX: http://vkbexternal/VKBWebService/ViewContent.aspx?scid=KB;EN-US;946517

    If the problem still persists please open a support case.

  • problem solved... it was proxy related, not moss related :)

  • I have same issue (events 7076, 6398 and 6482, IIS 7 manager is working, IIS 6 manager is not) in Windows Server 2008 and IIS 7.

  • We are also seeing this running sharepoint 64 bit on windows 2008

  • Hi Ian,

    then please open a support case for this so that we can escalate this and request a hotfix.

    Cheers,

    Stefan

  • Hi Stefan,

    Cheers

  • Does anyone know of a fix for IIS 7 and Server 2008?

  • Hi Mike,

    till now nobody requested a fix for this for IIS 7 from Microsoft. So no hotfix has been created till now.

    If you need it, please open a support case and request the fix for IIS 7 to ensure that it is created.

    Cheers,

    Stefan

  • There is a fix available now for Windows 2008 (and Vista), although the kb article at http://support.microsoft.com/default.aspx/kb/946517 does not list it.

    At the top of the article you can find the "View and request hotfix downloads" link. Here you can find a fix for Vista, which can also be applied to Server 2008. This has been confirmed by Microsoft Support. Vista and Server 2008 share the same code.

  • hi Stephan,

    My doubt is generic , how can we easily find whether a later version of MS update/Rollup includes its old fixes.

    For eg: I want to know whether this fix is included in MOSS SP2 or June COD patches ?

    Pleasehelp me...

  • Hi Sarath,

    this fix is for IIS - not for MOSS. So it cannot be included in any MOSS fixes.

    Cheers,

    Stefan

  • Hi Stefan,

    I am running into this issue, and I have windows 2008 sp1 with adsiis.dll version 7.0.6002.18005 which is a later version that what is listed in the hotfix.  I tried to install the hotfix anyway, but a message appeared that The update does not apply to your system.  Any ideas?

  • Hi Jenn,

    a similar hotfix exists for IIS 7.

    Please open a support case with the IIS team to request it.

    Cheers,

    Stefan
