Another way for forcing SQL Server to log the error messages related to deadlock is using the server-side trace, meaning that we have to turn on Trace Flags 1204 and 1222. This will ensure that above mentioned errors are logged, but in this way a quite verbose logging information will be...
Once you see where the locks are, here are some tips: ◦Deadlock frequency can sometimes be reduced by ensuring that all applications access their common data in the same order – meaning, for example, that they access (and therefore lock) rows in Table A, followed by...
While researching I was reading that installing VS 2010 sp1 will cause this issue in SSMS IntelliSense, but still working on finding the workstation owner and see if they having any problem in their SSMS intelligence, so I can conclude that is the issue and remediate the worksta...
In specific SQL Servers databases, I have deadlock problems that often result in significant performance degradation. When the deadlocks occur frequently in my environment, the deadlocks often become a performance killer for the overall application. If the deadlocks become severe enough, I need to dr...
tasks sometimes hang indefinitely, you can use this parameter to force a call to the task thread's interrupt() method if a task exceeds a set time limit. [c3p0 will eventually recover from hung tasks anyway by signalling an "APPARENT DEADLOCK" (you'll see it as a warning in the...

but only in production, not in staging. (This leads me to believe that there is something about our staging database -- possibly the volume of data, SQL Server 2012 vs 2005, or index tuning -- that differs from production in such a way that the deadlock is avoi...

rather than failing out after the specific time. In contrast, the overload of TryEnter that doesn't accept a time value defaults to using a timeout of 0, meaning that it will return false if the lock cannot be acquired immediately (again, our implementation will also throw an exception if...
