![]() If it never happens again, good it is solved, if not you have captured all the info. Let this trace run until the deadlock happens again, info is only recorded when a deadlock happens, so there isn't much overhead. On the other hand, deadlocks maintain the integrity of your data in highly concurrent applications. Figure out how to not have one of these locked and the deadlock will be resolved. On one hand, a deadlock will result in one of the processes falling 'victim' to failure. Look at the "resource list" section of the file, it will show what is being locked and held by each process causing the deadlock. Each process is contained, with an execution stack of procedure/trigger/etc calls, etc. Open this file in an xml viewer and it will be easy to tell what is happening. Try running the run a trace in the profiler (pick the blank template), select the "deadlock graph event", and on the new tab that appears (Events Extraction Settings), save each (check "save deadlock XML events separately") in its own file. WHERE -uncomment to not see this queryÄeadlocks are easily trapped with the profiler: JOIN sys.dm_exec_sessions s ON r.session_id = s.session_idĬROSS APPLY sys.dm_exec_sql_text (sql_handle) st You can set up the system to log deadlocks that occur in the SQL database. ,SUBSTRING(st.text, (r.statement_start_offset/2)+1,( (CASE r.statement_end_offset ,OBJECT_NAME(st.objectid, st.dbid) AS ObjectName ,LEFT(DB_NAME(r.database_id),50) AS DatabaseName ,LEFT(OBJECT_NAME(st.objectid, st.dbid),50) AS ShortObjectName ,r.cpu_time,r.reads,r.writes,r.logical_reads Try this query to see blocking processes, including the actual SQL query text: SELECT ![]()
