Blocking Issue

  • Hi,

    We got some blocking/dead lock issues in our servers. We have implemented once stored procedure, which will report on the blocking issues. We are getting the below errors/information

    DBCC INPUTBUFFER FOR SPID 662

    RPC Event

    0

    dbo.BFSDiagnosticLogDetailAdd;1

    DBCC INPUTBUFFER FOR SPID 677

    Language Event

    0

    IF @@TRANCOUNT > 0 COMMIT TRAN

    do you guys have any idea about the above. I appreciate your help.

    with smiles

  • Blocking locks and deadlocks are different things.  If you are getting deadlocks, you can enable the trace flags 1204, 1205 and 3605 to get more information - that way the deadlock trace files will give you much more information on what actually transpired in that deadlock.

    If you are troubleshooting blocking locks, then look up this script from PSS:

    http://support.microsoft.com/default.aspx/kb/271509/EN-US

    and use it to interpret your results.  The statements that you have given above are just input buffer information from two spids.  Take a look at that "BFSDiagnosticLogDetailAdd" object definition to see what it is doing and also at the same time spend time to record the output from the above PSS procedure to see what applications are involved and what kind of locks are being taken.
