XADM: Information Store Crash in UNK__Delete

View products that this article applies to.

Symptoms

The Microsoft Exchange Server 5.5 and Exchange 2000 Server information store may stop responding unexpectedly (crash). If Dr. Watson is active as the default debugger, a Dr. Watson log and a User.dmp file (if Dr. Watson is configured to create a User.dmp file) may be generated.

Cause

This behavior can occur because an individual OMSG is being released by the information store while the structure is still in use.
