BUG #: 15703 (SQLBUG_60)
BUG #: 16758 (SQLBUG_65)

SYMPTOMS

If a striped database dump runs into an operating system error (like error 112 -- out of disk space), an error 18001 may occur that can cause SQL Server to become unresponsive. The following is the message that is written to the errorlog:

Spid10 Process 10 entered sequencer without owning dataserver semaphore.

WORKAROUND

To work around this problem, either make sure that there is sufficient disk space available for the dump, or do not stripe the dump. For sample code to create an extended stored procedure that reports free drive space, see the following article in the Microsoft Knowledge Base:

164970 FIX: Disk Dumps May Cause Handled AV When Space Is Low
