SYMPTOMS

When you perform a backup in Microsoft Windows Server 2003 with Service Pack 1 (SP1), the backup application stops responding. This behavior occurs if the backup uses a volume snapshot.

CAUSE

This problem occurs because of an issue in the Volsnap.sys file. This issue generates a deadlock condition. In the deadlock condition, the system I/O is suspended. A file deletion operation is waiting for the system I/O to resume.
