Symptoms

The Exchange Server version 5.5 Service Pack 3 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: 
FramePtr  RetAddr   Param1   Param2   Param3   Function Name
