I've noticed a few days ago that SQL service on one of our servers had stopped. It's a virtual Server 2003 R2 in vSphere environment. I restarted the SQL Server service, but tomorrow morning I encoutered the same situation.
Subsequent log analysis through Event Viewer showed me that the first errors are always logged by VMware Tools - precisely 15 minutes after VSC backup job is initiated on that VM (during the night),
Which is then followed by SQL service stopping:
I have tried modifying VMware Tools configuration, by removing it's VSS support module, and running the VSC backup job manually - and it worked, at least the 1st time. But then it went back to the old routine. I don't know if it's worth mentioning, but Snapmanager for SQL is present and it's working fine.
Any ideas what might be the cause? Or where to start looking for one?
