Symptoms

The Exchange Server version 5.5 Service Pack 3 or Service Pack 4 message transfer agent (MTA) may stop unexpectedly with a call stack that is similar to the following when the MTA attempts to gain access to a particular object in the MTA database:

In addition, the MTA may log several event ID error messages that are similar to the following before the MTA stops unexpectedly:
