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:
Date Time SPID Error: 17066, Severity: 16, State: 1.
Date Time SPID SQL Server Assertion: File: <replrowset.cpp>, 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.
Date Time SPID Error: 3624, Severity: 20, State: 1.
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.
