Bug: #50001183 (SQL Hotfix)



Microsoft 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.



SYMPTOMS
When the Log Reader Agent runs for a transactional publication in SQL Server 2005, a SQL Server assertion is logged in the Errorlog file. When this problem occurs, error messages that resemble the following are logged in the SQL Server 2005 Errorlog file:

Error: 17066, Severity: 16, State: 1.

SQL Server Assertion: File: , line=2275 Failed Assertion = 'm_pSchema_re'. 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.

Error: 3624, Severity: 20, State: 1.



CAUSE
This problem occurs because an ALTER INDEX operation is rebuilding indexes while the Log Reader Agent is processing replicated transactions on an article. Additionally, this problem occurs when the ONLINE option for the ALTER INDEX Transact-SQL statement is set to ON.



Cumulative update information
To resolve this problem, obtain cumulative update package 2 for SQL Server 2005 Service Pack 2 (build 3175). For more information about how to obtain cumulative update package 2 (build 3175), click the following article number to view the article in the Microsoft Knowledge Base:

936305 Cumulative update package 2 for SQL Server 2005 Service Pack 2 is available



WORKAROUND
To work around this problem, set the ONLINE option for the ALTER INDEX operation to OFF.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
