SYMPTOMS

The MS Mail Connector Interchange (MSMI) may terminate unexpectedly with the following events reported to the application log:

   Event ID: 2380
   Source: MSExchangeMSMI
   Description:
   A memory access violation has occurred that prevents further processing
   of a message. The access violation that occurred is an attempt to read
   from 0x480df78. Please refer to the immediately following event(s)
   logged by MS Mail Connector Interchange  for more information on the
   message that could not be processed. (Exception address: 0x4496c2.)

CAUSE

The MSMI is freeing a block of heap memory before the actual process is done with it. When the process tries to access this freed area of memory, an access violation occurs.
