Microsoft distributes Microsoft SQL Server 2008, Microsoft SQL Server 2008 R2 or Microsoft SQL Server 2012 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008, SQL Server 2008 R2 or SQL Server 2012 fix release.

Symptoms

Assume that you run a parallel query in SQL Server 2008, in SQL Server 2008 R2 or in SQL Server 2012. When a query plan that is created by Query Optimizer uses a hash join for the parallel query execution, a "bufferLen >= colLen" assertion might occur. Additionally, a mini-dump file is generated in the SQL Server log folder, and the following error message is logged in the SQL Server error log file:

<Date><Time> <spid> Error: 17066, Severity: 16, State: 1.
<Date><Time> <spid> SQL Server Assertion: File: <e:\sql10_katmai_t\sql\ntdbms\storeng\dfs\access\sebind.h>, line=1139 Failed Assertion = 'bufferLen >= colLen'. This error may be timing-related. If the error persists after rerunning the statement, use DBCC CHECKDB to check the database for structural integrity, or restart the server to ensure in-memory data structures are not corrupted.

<Date><Time> <spid> * BEGIN STACK DUMP:
