Pieter commented on AMQ-1301:
-----------------------------
Unfortunately I get the same behaviour again. I can't find a reliable way to
restore a network of brokers after one broker is brought down, other than
shutting down all brokers and removing the data directories.
This specific behaviour is perhaps a bug in the loop detection? I could image
it gets a message from the broker, sees it as a new messages, and forwards it
again to the other broker, ad infinitum. In any case, not being able to restore
a network of brokers without problems makes the network practically useless.

> Key: AMQ-1301
> URL: https://issues.apache.org/activemq/browse/AMQ-1301
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 4.1.2
> Reporter: Pieter
>
> When using a network of brokers, I get problems in the following scenario.
> Consider two brokers, broker1 and broker2, connected to eachother (see config
> below). Everything works ok: durable consumers on topics get messages sent to
> either server. The messages are all persistent.
> The problems occur in this scenario:
> 1. Bring down one of the brokers, let's say broker2 (all consumers and
> producers connect to the other server, without any problems)
> 2. Start the killed broker2 again
> 3. The broker2 reconnects to the network as expected
> 4. However, messages don't get propagated correctly on the network anymore.
> Consumers on broker1 don't get messages sent to broker2 anymore, and messages
> from broker2 get sent to broker1 over and over again. This can also be seen
> in the webconsole for example, where the number of messages in the queue
> grows rapidly.
> The only way to fix this is to kill all brokers, and remove the persistent
> message stores. THis is unacceptable, since this loses messages.
