My System:
Queue Manager with JMS system queues used for Pub/Sub with MQSeries Pub/Sub broker. 1000+ users connected to QM using MQI channels. Any user can publish or subscribe.
Problem:
I am observing that SYSTEM.JMS.REPORT.QUEUE gets filled up and finally reaches its MAX limit. As a result new users cannot connect and existing connected users slowly slowly gets disconnected.
MY Interpretation:
SYSTEM.JMS.REPORT.QUEUE is used by publisher to get the Response of the publishing. And when my user tries to publish and QM finds that SYSTEM.JMS.REPORT.QUEUE was full it puts the message in DEAD LETTER QUEUE, as a result publisher assume that it fails to publish and assuming that there is some problem with MQ, my user disconnects (application logic for error handling)
So why JMS is not consuming the response or report messagees ? Any thing we missed on publisher ?

Further investigation shows that SYSTEM.JMS.ND.SUBSCRIBER.QUEUE have depth of 40000+
what's going on ?

Apparently you are asking for a report of confirmation of some sorts hence the REPORT.QUEUE. However are you handling this confirmation in any way?
Is there any process at all consuming the messages in this queue??
Enjoy  |

| Not yet. We would like to. Subscriber queue is getting filled and throwing errors. |

My bet is that there is something wrong and that you have subscribers that aren't deregistering. The other problem could be that you are publishing messages faster than you can pick them up. You might need to increase the maxdepth of the queues that you are dealing with. |
