Quick update... I re-ran my tests as suggested.
First my producer connected to amq4 and the consumer to amq1. That setup worked quite well without any error or timeout. Then I re-configured it again with messages being sent to amq1 and consumed from amq4. To my surprise it worked this time (I re-ran the test three times yesterday and all three failed the same way!). However, I noticed that when transmitting messages from amq1 to amq4, it appears that the bridge is slower than the other way around since I saw on average 10k pending messages in all queues - the other way around, there were on average less than 1,500 msg pending. On another note: I mentioned that I setup this environment in our private cloud infrastructure. This morning I saw a note from our infrastructure guys that we are having some network issues in that data center hosting this environment. It is certainly possible that my issues yesterday may have been a side-effect of the network problems. So, I will keep testing but for now, my suspicion is that it is likely to be a network problem and not an issue within ActiveMQ. I will follow-up in case the issue shows up again. Until then, sorry for potentially raising a false alarm. -- View this message in context: http://activemq.2283324.n4.nabble.com/Potential-Bug-in-Master-Slave-with-Replicated-LevelDB-Store-tp4686450p4686492.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
