How to Analyze "Deadlocked Schedulers" Dumps?

Do you see "Deadlocked Schedulers" errors similar to one below and stuck?

From SQL Server Errorlog

**Dump thread – spid = 0, PSS = 0×0000000000000000, EC = 0×0000000000000000

***Stack Dump being sent to C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG\SQLDump0001.txt

* BEGIN STACK DUMP:

* Deadlocked Schedulers

* Short Stack Dump

Stack Signature for the dump is 0x00000000000003D0

New queries assigned to process on Node 0 have not been picked  up by a worker thread in the last 60 seconds. Blocking or long-running queries can contribute to this condition, and may degrade client response time.  Use the "max worker threads" configuration option to increase number  of allowable threads, or optimize current running queries.  SQL Process Utilization: 0%. System Idle: 69%.

New queries assigned to process on Node 3 have not been picked up by a worker thread in the last 300 seconds. Blocking or long-running queries can contribute to this condition, and may degrade client response time. Use the "max worker threads" configuration option to increase number of allowable threads, or optimize current running queries. SQL Process Utilization: 6%. System Idle: 90%.

Cause

We get Deadlocked Schedulers error (New queries assigned to process on Node n have not been picked up by a worker thread in the last 300 seconds) and dump when Scheduler Monitor detects threads(workers) are not Progressing on schedulers of one (or) all nodes for 60 seconds (300 seconds in Denali) and there are new work request (tasks) but there is no idle threads to pick up the the work request and SQL Server could not spawn new thread to process the new work request (Max worker threads reached).

Some of common causes are most of the tasks are waiting on a single resource because of resource bottleneck, excessive blocking, excessive parallelism, very long running Queries executed by all workers, all threads waiting on trace write waits etc..

SQL Server will not accept new connections or cannot process new requests  when there is deadlocked scheduler condition (Exception: deadlocked condition on single node). 

Note: In systems with multiple nodes (NUMA)  If all the threads which belong to schedulers of single node is exhausted (or) Schedulers not progressing on single node can cause deadlocked scheduler condition.

Detailed explanation about dead lock schedulers can be found in This blog from my mentor J.P

Steps to analyze "Deadlocked Schedulers" Dumps.

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

Step 1:

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

Step 2:

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

Step 3:

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

Step 4:

Verify if symbols are loaded for  SQL Server by using the debugger command lmvm

0:002> lmvm sqlservr
start             end                 module name
00000000`01000000 00000000`03679000   sqlservr T (pdb symbols)          c:\websymbols\sqlservr.pdb\21E4AC6E96294A529C9D99826B5A7C032\sqlservr.pdb
    Loaded symbol image file: sqlservr.exe
    Image path: C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Binn\sqlservr.exe
    Image name: sqlservr.exe
    Timestamp:        Wed Oct 07 21:15:52 2009 (4ACD6778)
    CheckSum:         025FEB5E
    ImageSize:        02679000
    File version:     2005.90.4266.0
    Product version:  9.0.4266.0
    File flags:       0 (Mask 3F)
    File OS:          40000 NT Base

    Translations:     0000.04b0 0000.04e4 0409.04b0 0409.04e4

Step 5:

Type  ~*kL 20   and look at the stack of all the threads  to find what majority of threads are doing.

Note: If you find most of your threads are waiting on stack which is not listed below please paste the stack in comments session of this blog (or) In MSSQLWIKI  face book group we will try to answer you. If you don’t get prompt reply from the community, you may need to open a support ticket with Microsoft.

1. If it is blocking issue and If most of the threads are  waiting to acquire a lock you will find the most of the stack similar to one below. (We try to acquire lock and go to wait, since someone is holding a lock)

ntdll!ZwSignalAndWaitForSingleObject

kernel32!SignalObjectAndWait

sqlservr!SOS_Scheduler::SwitchContext

sqlservr!SOS_Scheduler::Suspend

sqlservr!SOS_Event::Wait

sqlservr!LockOwner::Sleep

sqlservr!lck_lockInternal

sqlservr!GetLock

2. If most of threads are stuck while trying to write profiler events to the destination you might find stack similar to one below

ntdll!ZwSignalAndWaitForSingleObject

kernel32!SignalObjectAndWait

sqlservr!SOS_Scheduler::SwitchContext

sqlservr!SOS_Task::Sleep

sqlservr!CTraceRowsetIoProvider::GetFreeBuffers

sqlservr!CTraceWriteRequest::InitForRowsetTrace

sqlservr!CTraceRowsetIoProvider::InitializeWriteRequest

sqlservr!CTrace::WriteRecord

sqlservr!CTraceController::ProduceRecord

sqlservr!CTraceData::TracePreBatchEvent

sqlservr!CSQLSource::Execute

sqlservr!process_request

sqlservr!process_commands

sqlservr!SOS_Task::Param::Execute

sqlservr!SOS_Scheduler::RunTask

sqlservr!SOS_Scheduler::ProcessTasks

3. If your stack’s  are like one below refer http://support.microsoft.com/default.aspx?scid=kb;EN-US;974205

sqlservr!SpinlockBase::Sleep
sqlservr!SpinlockBase::SpinToAcquire
sqlservr!TSyncHashTable_EntryAccessorsqlservr!CQSIndexStatsMgr::AddNewMissingIndex
sqlservr!CIdxSuggestion::Register
sqlservr!COptExpr::PqteConvert
sqlservr!CPhyOp_Top::PqteConvert
sqlservr!COptExpr::PqteConvert
sqlservr!COptExpr::PqteConvertTree
sqlservr!COptContext::PcxteOptimizeQuery
sqlservr!CQuery::Optimize
sqlservr!CQuery::PqoBuild
sqlservr!CStmtQuery::InitQuery
sqlservr!CStmtSelect::Init

4. If you see many stacks like the one below it could be BPOOL memory pressure (or) Lazy writer  waiting on I/O

sqlservr!BPool::Steal

sqlservr!SQLSinglePageAllocator::AllocatePages

sqlservr!MemoryNode::AllocatePagesInternal

sqlservr!MemoryClerkInternal::AllocatePages

sqlservr!IMemObj::PbGetNewPages

sqlservr!CSlotPageMgr::PbAllocate

5. If you see many stacks like the one below it should be because of excessive parallelism

sqlservr!CQScanXProducerNew::Open

sqlservr!FnProducerOpen

sqlservr!FnProducerThread

sqlservr!SubprocEntrypoint

6. If you see many stacks like the one below (Many threads waiting to flush log) it should be because of disk bottleneck’s. Check if you see "I/O requests taking longer than 15 seconds" messages in Errorlog before Deadlocked Schedulers Dumps. Refer Troubleshooting sql server I/O for troubleshooting I/O issues.

sqlservr!SOS_Event::Wait

sqlservr!SQLServerLogMgr::WaitLCFlush

sqlservr!SQLServerLogMgr::LogFlush

sqlservr!SQLServerLogMgr::WaitLogFlush

sqlservr!XdesRMFull::Commit

    So general question on this thread. I wanted to review a dump file from a server issue last night. So I download WinDBG to my local PC, install it, copy the file from my production server, and then start following the steps listed above. Following along exactly as above, I get the following:

    Loading Dump File [C:\Users\nathan.heaivilin\Desktop\DB9 Issue\SQLDump0074.mdmp]

    Any thoughts on what I am doing wrong here:
    My local PC is a Windows 7 64 bit install
    Production server is a Windows Server 2003 64 bit install
    SQL Server 2005 SP4 version

    Thanks,

    Nathan

    Karthick, thank you very much for the note. I was able to get that corrected. When redoing everything here is what I get.

    So to me, everything is working as expected. However, when I run your ~*lK 20 command above, I get a ton of data, nothing of which had any of the items in red above.

    Also, when running an !analze -v, I get the following.

    Hi Karthick,

    Thanks for your fantastic sharing which is very helpful. Actually I got this exact problem on my box and I used the tool “windbg” to troubleshoot. I did find the keywords “sqlservr!lck_lockInternal” and “sqlservr!SOS_Event::Wait” in the dump file. it seems to be related to lock and IO. However, I still want to know what I can do next to find the real culprit. Could you please give me some advice on that? Thank you very much.

    regards,

    Oliver

    • Hello Oliver,
      so we know it is because of long blocking chain. You should monitor the server for long blocking chain and fix it. If you would like to get the head blocker share the dump with me (If there is no restriction) I can get the head blocker for you form the dump.

  44. The one fighter I really want to see Matt face before he goes up against St Pierre
    again is Diego Sanchez. “I just turned 37 years old,” Ortiz said this past month
    in a mmajunkie. Fights can take place anywhere, not just on your feet, mixed martial artists have
    more to worry about than K1 kickboxers or boxers.

  45. This is really interesting, You are a very professional blogger.

  47. Every new amount borrowed requires another round
    of qualifying. Again, this is an ideal scenario, which means prolonging
    repayment will only result more interest paid and furthering your debt overall.
    You might wind up paying $15 to $26 in interest per $100 that you borrow.

  48. I almost never comment, but after browsing through a great deal of remarks on this page How to
    Analyze Deadlocked Schedulers Dumps? MSSQLWIKI. I actually do have
    a couple of questions for you if it’s allright. Is it only me or does it give the impression like a few of the responses look like they are written by brain dead people? :-P And, if you are posting at additional places, I’d like to keep up with everything fresh you have to
    post. Could you post a list of all of your social networking sites like your linkedin profile, Facebook page or twitter feed?
