Ok, you'll be glad to hear the memory leak was external to JMS. So I'm back to the problem where the bridges die after several hours idle time. I know I'm pushing on this, but I'd feel a lot better if I could see an 'Update JMessaging to 1.4.5.GA' task in the AS5 roadmap. Where would be an appropriate place to post on this?
