One of the channel went down and came back up right away as seen in mq logs. This looks like a sequence number issue. However there was no manual intervention to alter the sequence number. It looks to be resetting automatically and firing the channel up.
Local queue manager
--------------------------------
12/22/14 20:27:49 - Process(786790.1) User(mqm) Program(runmqchl_nd)
Host(XXXX)
AMQ9526: Message sequence number error for channel 'A.CHL'.
EXPLANATION:
The local and remote queue managers do not agree on the next message sequence
number. A message with sequence number 30 has been sent when sequence number
27 was expected. The remote host is '10.22.33.91(1417)'.
ACTION:
Determine the cause of the inconsistency. It could be that the synchronization
information has become damaged, or has been backed out to a previous version.
If the situation cannot be resolved, the sequence number can be manually reset
at the sending end of the channel using the RESET CHANNEL command.

| That is showing that the channel is retrying but it will not stay running until you reset the sequence number. |

Don't just reset the sequence number... Fix the problem as described in the infocenter

Maybe because I am tired but I can not see it being reset from the post. From the logs I see it saying that the sender channel is trying to use seq num 30 but receiver channel is trying to use 27.
Quickest way is to reset sequence number to be same on both ends, but as another post has indicated you may want to find out why it has changed. |

Reset it on the sender end of the channel. It then automatically sets it on the receiver end.
