SYMPTOMS

Consider the following scenario:
  • In Microsoft SQL Server 2005, SQL Server 2008, or in Microsoft SQL Server 2008 Service Pack 1 (SP1), you configure database mirroring between 2 databases.
  • You run the ALTER DATABASE command together with the REMOVE FILE clause to remove a transaction log file of the database on the principal server.
In this scenario, the Database Mirroring session is suspended and cannot resume, and you receive the following assertion:
Location: "logmgr.cpp":3350
Expression: headLFCB->lfcb_startOffset < fcb->GetSize () * (ULONGLONG)PAGESIZE

Additionally, the following error messages are logged in the SQL Server error log file:
<Date><Time> spid23s **Dump thread - spid = 23, PSS = 0x0000000082FBAB60, EC = 0x00000000837E81C0

Assertion = 'headLFCB->lfcb_startOffset < fcb->GetSize () * (ULONGLONG)PAGESIZE'. 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> spid23s Error: 3624, Severity: 20, State: 1.
<Date><Time> spid23s A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a QFE from Technical Support.
<Date><Time> spid23s Error: 1454, Severity: 16, State: 1.
<Date><Time> spid23s While acting as a mirroring partner for database '<databasename>', server instance '<instancename>' encountered error 3624, status 1, severity 20. Database mirroring will be suspended. Try to resolve the error and resume mirroring.
<Date><Time> spid23s Database mirroring is inactive for database '<databasename>'. This is an informational message only. No user action is required.
