The Microsoft Exchange Information Store service may stop responding when you try to back up your Exchange 2003 database files by using a program that uses the Volume Shadow Copy Service.

Symtoms:-

This problem occurs when the following conditions are true:

The computer is running Microsoft Exchange Server 2003 Service Pack 1 (SP1?). The program that you use to back up the database uses the Volume Shadow Copy Service in Microsoft Windows Server 2003. You dismount the database after the Volume Shadow Copy Service backup is finished.

Cause :-

This problem occurs because of a deadlock condition that may occur when you dismount the Exchange database after the Volume Shadow Copy Service backup operation is finished.

This deadlock condition occurs if all the following conditions are true:

The freeze period of the Volume Shadow Copy Service backup operation starts. During this freeze period, Exchange receives a commit operation, or Exchange receives another operation that performs logging and that then waits for the log files to be flushed. You dismount the Exchange database after the Volume Shadow Copy Service backup operation is finished.
