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:

   

   FramePtr  RetAddr   Param1   Param2   Param3   Function Name
   0ab1fcfc  00510cc7  cffa119e 07ad9838 0069578c EMSMTA!otpmralt+0x25

   0ab1ffec  00000000  00000000 00000000 00000000 KERNEL32!BaseThreadStart+0x51

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

   Event ID: 9202
   A sockets error 0 on an accept() call was detected. The MTA will attempt to
   recover the sockets connection. Control block index: 203. [BASE IL TCP/IP
   DRVR 8 256] (12)

   Event ID: 9405
   An unexpected error has occurred which may cause the MTA to terminate. Error:
   Failed to find socket, result=14, count=63. [BASE TCP/IP DRVR 122] (16)
