Every now and then, the MessageListener simply doesn't get any more messages and we have to restart the application for a reconnect despite the failover protocol (as seen above). We've tried various connection URI parameters but so far, the issue keeps popping up every few weeks. I somehow doubt it has to do with some timeout because, yesterday, it happened during the day during normal business, not in the night after hours of inactivity.

Most of the messages are being delivered to the remote broker instead of being shared between the network connector and the broker's consumer. If a broker has 5 consumers and 1 network connector, and receives 50 messages, it processes 5-10 in its consumers and the rest outside We are using prefetch = 1 for the consumers, so we set prefetchSize=1 for the network connector. We have tried both with and without conduitSubscriptions. The only configuration that have worked was setting a high prefetch in consumers and network connector, but that was only for testing purpose, as we cant modify the consumer's prefetch size. So we need to know if there's any way to make it work with prefetch = 1 in the consumers. The expected behaviour in the case explained before would be processing 25 messages in the broker's consumers and send 25 to the network connector.

The default strategy for determining whether the current master has failed is for the secondary server to attempt to get a lock on the database table, waiting indefinitely for the lock to be granted. This is not working (at least in our context) as, after a relatively short time in operation (a handful of hours at most) the connection to Oracle is dropped. Activemq doesn't notice this, so the secondary sits there happily waiting for a lock it can now never get and, in the event of a failure, won't serve any clients as it is not a master. Is there some way to change the decision mechanism to, eg, a polling strategy? Or can anyone suggest another resolution to this problem?

Here's our setup: - N copies of a producer application; each copy of the producer application consists of an embedded broker with 2 network connectors pointing at an embedded broker in the consumer application - 1 consumer application; the consumer application consists of an embedded broker with 2 transport connectors Messages in the consumer application are sent to the embedded broker, which pushes those messages to the embedded broker in the consumer application over the network/transport connectors, and are consumed by listeners on the embedded broker in the consumer application. In AMQ 5.4.0, the name of the network connectors in the embedded broker in the producer application were not required to be unique across copies of the application, ie. for each copy of the producer application used the same name for each network connector.

The setup I have is I have two brokers, A and B. I also have two consumers on B subscribed to two topics, topic1 and topic2. I then have two producers on A which are publishing on topic1 and topic2. So when I startup the consumer on B on topic1 and have it consume messages slowly, and then I produce a large number of messages to topic1 on A so that producer flow control is triggered and the producer on A is held back from sending more because of this. I then start the consumer on topic2 on B and have it consume quickly. When I produce to topic2 on A the messages do not flow like they should. Rather they hold on the networkConnector until 5 messages make it to topic1 and then 5 messages all get sent right away to topic2. It seems like this burst of messages always matches the prefetchSize of the networkConnector.
