Assume that you create a query session to a database that contains Memory-optimized tables and table types. When you run a query against the sys.sysindexes view of the database, the query session is terminated. Additionally, you receive an error message that resembles the following:

Msg 3624, Level 20, State 1, Line 12
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 11
Cannot continue the execution because the session is in the kill state.
Msg 0, Level 20, State 0, Line 11A severe error occurred on the current command.  The results, if any, should be discarded.

Note If you run DBCC CHECKDB on the database to check for database corruption, there is no error reported.
