Symptoms
Assume that your application makes a chain of multiple stored procedure calls, with one of the participants being a common language runtime (CLR) stored procedure that calls a T-SQL stored procedure with an OUTPUT large object argument ([N]VARCHAR(max) or VARBINARY(max)). In certain circumstances, this CLR call may result in an error that resembles the following:
Msg 3624, Level 20, State 1, Procedure ProcA, Line 0 [Batch Start Line LineNumber]
A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a Hotfix from Technical Support.
Msg 596, Level 21, State 1, Line LineNumber
Cannot continue the execution because the session is in the kill state.
Msg 0, Level 20, State 0, Line LineNumber
A severe error occurred on the current command. The results, if any, should be discarded.
