Hello,
I recenlty upgraded My SQL 2005 server to SQL 2012 SP1. The system_health in Extended Events is now continuously reporting the event listed below.
After upgrading to SQL 2012 SP1 I installed a second instance on the same server. This instance does not report the same event.
Any help would be welcome.
