Non-yielding IOCP Listener, Non-yielding Scheduler and non-yielding resource monitor known issues and fixes

  • Artigo

 

Do you see below errors in SQL error along with dumps and stuck?

New version of this post in available in This Link

 

Non-yielding IOCP Listener
* BEGIN STACK DUMP:
*   05/06/12 03:54:59 spid 0
* Non-yielding IOCP Listener

Non-yielding Scheduler
* BEGIN STACK DUMP:
*   04/16/12 10:09:58 spid 6256
* Non-yielding Scheduler

Non-yielding Resource Monitor

* BEGIN STACK DUMP

*   01/22/09 19:11:16 spid 0

* Non-yielding Resource Monitor

 

Refer How to analyze Non-Yielding scheduler or Non-yielding IOCP Listener dumps  for analyzing the Non-yielding Scheduler, Non-yielding IOCP Listener and Non-yielding Resource Monitor

If you are interested in just finding a quick resolution follow the below steps to get the Non-Yield stack from the dump and check if it is matching with any existing known issues in SQL Server.  

To analyze the dump download and Install Windows Debugger from This  link

1. Open Windbg

2. Choose File menu –> select Open crash dump –>Select the Dump file (SQLDump000#.mdmp)

3. on command window type    
.sympath srv*c:\Websymbols*https://msdl.microsoft.com/download/symbols;

4. Type .reload /f and hit enter. This will force debugger to immediately load all the symbols.

5. Type  .cxr sqlservr!g_copiedStackInfo+0X20 for SQL Server2005 and SQL Server2008/2008R2  (or)   .cxr sqlmin!g_copiedStackInfo+0X20  for SQL Server2012.

Type kc 100 and look at the stack to see if it matches with the stack of any of known issues in SQL Server listed below.

If kc 100 doesn’t display any stack and throws “WARNING: Frame IP not in any known module. Following frames may be wrong” type .cxr to reset to default scope and try .cxr sqlservr!g_copiedStackInfo+0X00c (In 32-Bit (X86) SQL server valid offset for context is 0X00c Look at This blog to see how we identified the offset)   

6.  Type kc 100 and look at the stack to see if it matches with any of the known issues in SQL Server.

    Patz, Check your disk performance. SQL Server is trying to print "i/o requests taking longer than 15 seconds to complete on file" toerrolog file and there is delay writting to errolog file as well.  Fix the disk performance You can follow the steps in below blog. mssqlwiki.com/.../io-requests-taking-longer-than-15-seconds-to-complete-on-file

    Diane, This issue is because of a know issue and already fixed. Apply the latest SP and CU for SQL2005. It will solve your issue.
