Error description
A batch of messages is sent from an application to a queue manager. Trace shows the messages arrive in the correct order. However, when the messages are delivered, they are out of sequence. Example: Message ID ending in 20111d74 arrives. Followed by message ID ending in 20111d76. When delivered, 20111d76 is delivered first. Followed by the delivery of 20111d74. . This does not comply with the MQ 7.1 InfoCenter: Configuring Connecting applications using distributed queuing WebSphere MQ distributed-messaging techniques Channel message sequence numbering Sequential retrieval of messages . This can be recreated by having more than one application (browse and destructive get applications) waiting to get message from the queue.
Local fix
