Code that was working fine last week is suddenly throwing this exception:
System.Data.SqlClient.SqlException (0x80131904): Warning: Fatal error
605 occurred at [date / time]. Note the error and time, and contact
your system administrator.
We are running .NET Framework 4.0 on SQL Server 2008 R2 and this exception is thrown while running a stored procedure.
In the end all we had to do was to make sure all the Service Packs and Cumulative Updates were installed on the SQL servers.
