SQL Server 2008 Agent keep stopping for unknown reason My MSSQL 2008 service keep stopping don't know why. I took the habit to just restart the service, but it's getting really annoying.

Does anyone has a clue on why it keeps shutting down ?

Sql server 2008, logged as local.

Here are 4 SQLdump from today.

found this in my event viewer : 


  SQL Server is terminating because of fatal exception c0000005. This error may be caused by an unhandled Win32 or C++ exception, or by an access violation encountered during exception handling. Check the SQL error log for any related stack dumps or messages. This exception forces SQL Server to shutdown. To recover from this error, restart the server (unless SQLAgent is configured to auto restart).
