Hi Thanks for that. I've found the QueueBrowser call and that looks promising, though I'll do some investigation next week into the queue itself

If there are messages in the queue but you aren't receiving them then you are either subscribing to the wrong queue or there's possibly another consumer on the queue with a large prefetch buffer set and is holding the contents hostage. You need to do some investigation into what's going on at the broker end as well as on your client(s). -- Tim Bish twitter: @tabish121 blog: http://timbish.blogspot.com/ ________________________________ If you reply to this email, your message will be added to the discussion below: http://activemq.2283324.n4.nabble.com/Apache-NMS-ImessageConsumer-ReceiveNoWait-not-returning-a-message-tp4727286p4727289.html To unsubscribe from Apache NMS ImessageConsumer.ReceiveNoWait() not returning a message, click here<http://activemq.2283324.n4.nabble.com/template/NamlServlet.jtp?macro=unsubscribe_by_code&node=4727286&code=cm9nZXIuYWxsZW5AbmV0d29ya2NlbnRyaWNzdXBwb3J0LmNvbXw0NzI3Mjg2fDE3MTA5ODg3MDE=>.
