MORE INFORMATION
================

You will need to restart the MTA and it should continue to process mail without
further incident.

The call stack when viewed through a debugger might be similar to the following:

FramePtr  RetAddr   Param1   Param2   Param3   Function Name
0698fd50  020b7ad1  e0050c08 00000000 00000000 KERNEL32!RaiseException+0x6a

KERNEL32!BaseThreadStart+0x61

The final critical error occurred in oxpginfo(). This passed the error code (C08
hex = 3080 decimal) up the call stack where the exception was raised. The
unexpected termination of the MTA might have been caused by an XAPI entity
deletion being performed.
