Using 'dbghelp.dll' version '4.0.5'

  • Hello,

    This isn't specific to SQL 2012 after doing a bit of Googling, but it's writing to my Sql Server log roughly once every 5 seconds so pretty annoying.

    We've just installed sharepoint portal on it. Any ideas how I can fix it please?

    thanks

  • I get the same error only in the context of a stack dump or login failure. Eg:

    Using 'dbghelp.dll' version '4.0.5'

    The client was unable to reuse a session with SPID 52, which had been reset for connection pooling. The failure ID is 46. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message.

    ***Unable to get thread context for spid 0

    * BEGIN STACK DUMP:

    * 12/05/12 14:03:06 spid 6388

    *

    * Non-yielding Scheduler

    * *******************************************************************************

    Stack Signature for the dump is 0x00000000000001AE

    External dump process return code 0x20000001.

    External dump process returned no errors.

    Process 0:0:0 (0x19cc) Worker 0x000000001BE801A0 appears to be non-yielding on Scheduler 1. Thread creation time: 12986879138906. Approx Thread CPU Used: kernel 0 ms, user 0 ms. Process Utilization 0%. System Idle 88%. Interval: 70308 ms.

    Are there any other errors reported?

  • Hi, This is cause by the extended events monitoring for Sharepoint 2012

    In SQL2012, you can find this Sharepoint diagnostics session under the extended events tab.

  • Thanks for your reply.

    I found the problem went away when installed SQL2012 SP1 ...
