FIX: Failed assertion and many access violation dump files after the sp_replcmds stored procedure is canceled in SQL Server

S’applique à : SQL Server 2012 DeveloperSQL Server 2012 EnterpriseSQL Server 2012 Enterprise Core

Symptoms


The log reader agent or the CDC scan job executes the sp_replcmds stored procedure to return commands marked for replication. In Microsoft SQL Server, if the stored procedure is canceled during execution, a failed assertion that resembles the following may be logged in the SQL Server error log:

Error: 17066, Severity: 16, State: 1.
SQL Server Assertion: File:< replicat.cpp>, lineNumber Failed Assertion = 'db_mem'. 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.

Additionally, multiple access violation dump files are created after the failed assertion dump.

Resolution


This issue is fixed in the following cumulative updates for SQL Server:

Cumulative Update 6 for SQL Server 2016 RTM

Cumulative Update 3 for SQL Server 2016 SP1

Cumulative Update 5 for SQL Server 2014 SP2

Cumulative Update 8 for SQL Server 2012 Service Pack 3

 

Status


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
