IJ10803: With XMS .NET if the MQMD is corrupted a rollback puts the message back in the original queue not to the backout queue.

APAR status

• Closed as program error.

Error description

• XMS .NET application should always send a poison message to the
  backout if the backout threshold limit is reached and backout
  queue is defined.

  to send the message to the backout queue.

  PROBLEM DESCRIPTION:
  XMS .NET application should always send a poison message to the
  backout if the backout threshold limit is reached and backout
  queue is defined.
  
  But if the data length of a poison message is 0 then XMS fails
  to send the message to the backout queue. XMS rollsback the
  message to the queue which is incorrect behavior.
  

Problem conclusion

• If backout threshold limit is reached and backout queue is
  defined XMS should always send the message to the backout queue.
