Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of the IBM MQ AMQP service.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  When messages were picked up from a queue manager and delivered
  to an AMQP client, the message IDs of the delivered messages did
  not always match the original message IDs of the messages at the
  time they were removed from the queue or topic. If several
  message were delivered at once to a waiting client, it was
  possible for all or some of those messages to be delivered with
  the same message ID.
  

Problem conclusion

• The IBM MQ AMQP Service has been updated so that the individual
  message IDs of each message delivered to an AMQP client now
  always matches the original message ID.
