One way is to look at the code that creates them, e.g. Destination tempDest = session.createTemporaryQueue();
My gut tells me there should be a way to tell from JMX, but there's none described on the JMX wiki page, so maybe not. Someone else may know of another way to tell. But since you added a setting related to allowing temp queue auto-creation and the behavior changed, I'd guess they are. Kevin Burton is the person on the list who's worked most heavily/recently with destination GCing, so I hope he'll jump into the discussion with some insight into what might be causing the behavior you're seeing. Sorry - I don't know if they are temp queues or not. How do I tell? From the ComTypeDefinition that they are created from? -- View this message in context: http://activemq.2283324.n4.nabble.com/Queue-Delete-not-working-in-5-8-tp4696159p4696249.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
