It’s happened a second time today, and we will be having a all hands on deck (WinTel, DB and Network team) to go through all possibilities. dug a little more and found the xp_logininfo is the last call from the hung session. http://msdn.microsoft.com/en-ca/library/ms190369(v=sql.100).aspx leads us back to the DC/s restarting.

We know the cause is due to a Domain Server restart. However, the process never stops and eventually consumes the TempDB and causes SQL Server to hault. the transaction is being ran by the SQLAgent – Job Manager by the service account, and is checking the sp_sqlagent_has_Server_Access. I cannot rollback/kill this transaction. Only success has been to restart the SQL Services. This has only been seen in our Dev environment, but today I’m seeing it in Production. Any further suggestions?

Your book SQL server Waits stats Joes 2 pros, is a very good book I really liked it

I have a small question, as you said Sql server by default is non- premeptive mode(Co operative mode)
I executed a query in one session which suppose to take some time to execute

in an another session I queried SYS.SYSPROCESSSES with spid as current session and previous session

What I found was for previous session the wait type was Preemptive , and status was runnable, which should be non preemptive and runnable according to our disscussion note (query in the previous session was still executing)

I am using SQL server 2008

can you please explain sir

Thank you

I am seeing on quite some new SQL 2008 R1 clusters the following wait typ;

wait_type wait_time_s pct running_pct
PREEMPTIVE_OS_AUTHENTICATIONOPS 7528.53 11.56 35.52

The servers are hosting the sharepoint databases of our enterprise. I have no clue how to debug this further.

Nice blog you have!
