I noticed a strange phenomenon with 6.0 client JAR's. A client that I have has 2 incoming queues (each handled by its own asynchronous session) and one outgoing queue (handled by a separate syncronous session) When application is idle and I try to shutdown it, it takes literally minutes to close JMS connection. With 5.3 JAR's it was instantaneous. Shutdown is done by a separate thread. It looks like connection is waiting for some kind of timeout(s). It would be nice to have a generic way to interrupt blocked JMS threads. Any insight/advice would be appreciated. - Thanks.

| I originally was just closing the connection. The issue got resolved as soon as I first started closing in a sequence all receiver channels, then all receiver sessions, then sender channels, then sender sessions, and only then the connection. Interesting observation: it takes 5 sec per asynchronous receiver channel to close (I guess this is the get-wait timeout). Everything else closes instantly. So total shutdown time = 5 sec * number_of sync_receivers. |
