Bug: #50000948 (SQL Hotfix)
NoticeMicrosoft distributes Microsoft SQL Server 2005 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 2005 fix release.
This article describes the following about this hotfix release:
When you use Replication Monitor to monitor the distribution database in Microsoft SQL Server 2005, the SQL Server 2005 database engine repeatedly generates failed assertion errors. Additionally, the session of Replication Monitor is disconnected temporarily. When the failed assertion errors occur, you experience the following problems:
If you experience the problem when you are running some Transact-SQL statements or some stored procedures, the Transact-SQL statements or the stored procedures run successfully if you reconnect to the instance of SQL Server 2005 and then run the Transact-SQL statements or the stored procedures.
If an application cannot connect to the instance, you can reconnect successfully to the instance.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
This issue only temporarily affects replication performance. This issue is not fatal to the SQL Server 2005 database engine. This issue has no lingering side effects. Additionally, this issue only occurs at certain times and in certain situations. If you retry the same command, the operation will probably succeed.
To determine whether you are experiencing this problem, open the SQL Server Errorlog file. If you have this problem, you see the following text:
At the time of the assertion, a minidump file is generated in the following folder:
Failed Assertion = 'LCK_SUCCESS (result)'
Drive:\Program Files\Microsoft SQL Server\MSSQL.x\MSSQL\LOGNote MSSQL.x is a placeholder for the instance ID for the instance of SQL Server. You can determine the corresponding value for the system from the value of the MSSQLSERVER registry entry in the following registry subkey:
If this issue frequently occurs, you can delete or archive old minidump files from the LOG folder to free drive space.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\SQL\
The SQL Server Errorlog file displays the problem command, a stack dump, and the assertion condition.
For example, you can find the problem command by using the following text in the SQL Server Errorlog file:
The problem command may vary. Additionally, the source code line number of the assertion may vary between versions and platforms, such as the 32-bit platform and the 64-bit platform. The failed assertion condition that matches this issue is the LCK_SUCCESS (result) condition.
