Hello all -

I have a JMS developer with an OpenInputCount of 1 on one of his message queues, after all of his connections are closed. I'm not very familiar with JMS, but I double-checked that they were explicitly calling the close methods for each QueueReceiver they were using.

Bouncing the queue manger cleaned it up but we are curious if anyone has seen this before.

It's a JMS client connection to MQ 5.2 (CSD04) on NT.

Thanks in advance.

Scott

I have seen lots of orphaned queue handles.

This particular group is using the OpenInputCount / OpenOutputCount to verify the number of connections ... what can be done to clean up the orphaned handles short of bouncing the queue manager?

Better yet, is there a way to prevent them?

Thanks.

Well the only way to prevent them from happening is not to kill process
or have apps not do a MQCLOSE/MQDISC. Currently the only way to clean them up is to bounce the queue manager. However on the new
version v5.3 there is a way to display what process has a Queue open
so this may help solve the problem.
