Recently upgraded to 9.3.0.4, heavily loaded 3 partner sender channels from 3 different systems from same datacenter reported TCP/IP timeouts on 3 different occasions while trying to send messages to this upgraded systems. there is no pattern.

upon checking the upgraded system, we could see AMQ9528W: User requested channel 'XXXXX.XXXX' to be stopped. whereas there was no manual stop was ever involved.

no FDC's. Trying to understand why same 3 senders fail connecting to the upgraded system with same error each time.

Only commonality is all three senders have heavy traffic(for MQ its not heavy) but in comparison to the other partners connecting to the upgraded system that never failed.

Anyone have come across with "AMQ9528W: User requested channel 'XXXXX.XXXX' to be stopped" whereas without significant evidence of manual stop/Kill/FDC's? could be a bug? thoughts please.

I have IBM looking into my case but need your expert views.

Any other errors written to the log at either/both ends of the channel? Channel Events enabled at both ends of the channel?

hi...there is a similar issue reported at 9.1 level

https://www.ibm.com/support/pages/apar/IT32481

so worth crosschecking your MQ version level

Thank you for your responses, I see same issue was discussed here without an solution.

http://mqseries.net/phpBB/viewtopic.php?t=44186&postdays=0&postorder=asc&start=15&sid=f06bfbe8139380f4bc036192b7c5a9fd

managed to collect trace when the user requested issue surfaced. here is the glimpse from the trace. IBM is saying a human have stopped channel

| Program Name :- amqrcmla |
| Arguments :- -m ******_QM.UAT -o STOP -c CHannel_Name |
| T -f 2 -a STOPPED

One thing is for sure, human hasnt issued a stop

No FDC, no pattern. just it occurs randomly.

When you opened a PMR with IBM, what was their solution?

I think IBM means that someone issued MQSC or PCF to stop the channel. This invokes the amqrcmla process to handle the stop and update the channel status table. I believe amqrcmla was introduced in MQ v6.0.
