SYMPTOMS

When you try to back up your Microsoft Exchange Server 2003 database files, the Microsoft Exchange Information Store service may stop responding. 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.
Under these conditions, the operation that Exchange receives enters the buffer in Exchange. However, the signal to flush the log file does not run because of the Volume Shadow Copy Service freeze. When the freeze is finished, the thread that performs the thaw operation does not try to flush the log. Therefore, the operation that Exchange receives waits indefinitely. Because of this, the Microsoft Exchange Information Store service stops responding.
