Error description

• An 0xC0000005 exception (ACCESS_VIOLATION) occurred on a Windows
  2003 RTEMS whenever an AIX HTEMS would go down (ITM 6.2.2 FP01
  being used).  Based on information found in the documentation,
  this is a storage overlay problem, which is covered by CMVC
  defect 124429.  All documentation (crash dumps) showed a stack
  corruption with text data:
  WARNING: Frame IP not in any known module.  Following frames may
  be wrong.
  

Local fix

• N/A
  

Problem summary

• The management server terminates abnormally with an access
  violation error in function OpLogReader::SetMSG2EmitBuffer().
  
  The management server generates an "access violation" exception
  with the following call stack:
  
  #0  0x00000200006089e6 in memcpy () from /lib64/tls/libc.so.6
  #1  0x0000020004c4ec9e in OpLogReader::SetMSG2EmitBuffer () from
  /products/ITM621/ls3266/ms/lib/KRANDREG
  
  The exception occurs when the management server attempts to
  write a MSG2 message exceeding 255 characters into the
  management server OPLOG table.
  

Problem conclusion

• Code changes were made to ensure that only 255 characters are
  written to the management server OPLOG table.  If an agent
  generates a message exceeding 255 characters, the message will
  be truncated.
