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

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

External dump process returned no errors.
Date Time Server Process 0:0:0 (0x31e8) Worker 0x000000016F41d140 appears to be non-yielding on Scheduler 4. Thread creation time: 12010668087858. Approx Thread CPU Used: kernel 2 ms, user 60516 ms. Process Utilization 11%. System Idle 83%. Interval: 71227 ms.

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 Dumps.

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

Step 1:

Open Windbg

step 2:

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

Step 3:

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

Step 4:

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

Step 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)

Note:If your stack doesn’t match with any of the stack  listed below then paste the stack in comments session of this blog (or) In This face book group.We will try to find the cause for you. If you don’t get any prompt reply from the community, you may need to open a support ticket with Microsoft.
