Folks - when you notice the broker in a 'stuck' state, please take a thread and heap dump before killing the broker process and share with devs on here.
Also: 1. What broker topology are you using? 2. How many producers/consumers? 3. Are you pooling connections, producers, sessions? 4. How large are your messages? 5. How many concurrent connections? What is the rate of message flow /second? 6. Are messages persistent and if so, what store? 7. What are your system/memory usage settings? How much heap and RAM on brokers and on clients? 8. What is the prefetch size? 9. How are you using the broker - what role is it playing in your system? Using queues, topics, both? 10. Have you monitored GC activity on clients and brokers? 11. What amq transport are you using and via what client? There might be more than one factors at play here. Very curious how restarts are 'fixing' the problem.
