We are using WMQ5.3 CSD07 in Solaris 9, with MA0C as the msg broker. And the application that does pub/sub is written in JMS.

Very occasionaly it happened that, the app has been successfully publishing to the broker, and then got "Broker No Response" error. When I checked the broker status using "dspmqbrk". it showed "running". I noticed that there were a few msgs queueing up in the stream queues (not the SYSTEM default stream, but hopefully it doesn't matter).

I then shutdown the app and tried "endmqbrk", which was hanging for a long time. After I did "endmqm", the hanging "endmqbrk" process then terminated. After "strmqm" and "strmqbrk", the broker went back into a fine running state.

Has anyone had similar experience? Is there a better way for me to bounce the broker, without bouncing the qmgr? Or is there any know "defects" of this MA0C?

Thanks.

Are you publishing and subscribing on the same Qmgr?

Yes, pub and sub are done with the same qmgr.

Actually this is what I got from IBM:

But since the occurence of this problem was so random and hard to replicate, I can only hope that this is in deed the solution.

Thanks.
