Hi,
3 days back, a support engineer notified us that all the services of 2 Database Servers at our data center had Mysteriously Shutdown. and they had to restart them manually. well, we had a look in the Error Logs, SQL Server Logs and even Event Logs. but couldn't
find anything strongly suspicious. the 2 servers had shutdown almost at the same time ( apprix. 2 mins difference between the shutdown times). yesterday, there was another server with the same symptoms.
here are the facts i found. Date : 4/12/2011
