SYMPTOMS

When you query the sys.dm_broker_activated_tasks dynamic management view (DMV) in Microsoft SQL Server 2005 or in Microsoft SQL Server 2008, you may experience the assertion failure that has SQL Server error code 3624. Additionally, dump files are generated in the SQL Server log folder, and the following error messages are logged in the SQL Server log file:
<Date Time> <SPID> Using 'dbghelp.dll' version '4.0.5'
<Date Time> <SPID> **Dump thread - spid = 7629, PSS = 0x00000003B76FCB60, EC = 0x00000003B76FCB70
<Date Time> <SPID> ***Stack Dump being sent to C:\SQL Server\MSSQL.1\MSSQL\LOG\SQLDump1109.txt

...
<Date Time> <SPID> Error: 3624, Severity: 20, State: 1.
<Date Time> <SPID> 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 QFE from Technical Support.

CAUSE

This problem occurs because of an issue that occurs when the DMV is implemented in SQL Server. Specifically, the number of rows that should be included in the query result set is miscalculated.
