PI50847: WMQ ABEND0C4 CMQXRUAR 00766 DURING MQ ACTIVITY REPORT/TRACE ROUTE PROCESSING

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• ABEND0C4 00000011 in CMQXRUAR +00766. Change Team finds
  that rriPutTraceRouteReply invokes cccGetBufferMem to get a new
  buffer for the trace route reply message, but this causes
  ReplyMsgLen to be updated to the maximum size of the
  destination reply buffer. However, this may be a lot larger
  than the source buffer, in which case the 0C4 can occur.

  ****************************************************************
  An incorrect length is being used during the copy of the
  activity report to the reply message buffer.  This results in a
  reference of storage past the source message buffer, which can
  result in an abend 0C4.
  

Problem conclusion

• The code has been changed to correct the length being used in
  the copy of the message.
