Resolution:

There is no way we can guaranty to get the creator of the temporary queue, because the creator may already be gone.

In a request/reply scenario, the requestor usually is the creator.

1. run "show stat consumers queue=&ltname>/show stat producer queue=&ltname>" to get the connection ID and user name.
2. run "show connections type=q user=&ltuser name>". to get host name and user name or ClientID to help you narrow down the problem.
3. after EMS 4.4, run show queue &ltTMP queueName>, you can get connectionID information.
