Hi

We have encountered a problem in our Production MQ server. It shows error as "AMQ8722: Dead-letter queue handler unable to put message: Rule 2 Reason 2085"

After that the Qmanager went to Preemptive state. And later we restarted the QManager and now its running fine. Can anybody helps me to find out the root cause.

where 2085 means MQRC_UNKNOWN_OBJECT_NAME, thats the reason DLQ failed here...

What queue is there in the RULE?

As this happened on a Production Stystem. so you should investigate it throughly....

Please verify the RULE of DLQ handler to find out which queue it is trying to put the message and why it failed to do so.

1 whats there in the logs / Any FDC etc?

What's "it" in this context? The obvious problem is the dead letter handler is trying to put to a queue that doesn't exist (possibly a dynamic queue that's gone out of scope). Your DLH rules should be written to prevent this kind of circular logic.

You've got a rule error, non-persistent messages and a fair amount of luck. I'd revisit how you handle messages on the DLQ.
