Running SQL Server 2008 R2 SP2 V.10.50.4000. (this is not a CTP as suggested in the 'Version' drop-down while completing this form)
Database mirroring is suspended. Stack dump occurs and SQL Error log reads:
SQL Server Assertion: File: <loglock.cpp>, line=807 Failed Assertion = 'result == LCK_OK'. This error may be timing-related.
I'm running database mirroring in high performance mode. Applied SP after previously experiencing this error and referring to http://support.microsoft.com/kb/974319?wa=wsignin1.0.
Problem has re-surfaced. I have multiple databases mirrored but this issue will occur on a single database, seemingly at random.
