I wouldn't expect the consumer on L2 to receive any of them Hmm... Sometimes it receives all, sometimes some messages. I have been testing by sending 10 messages at a time, 5 are queued to L1-Q1 and 5 are queued to L2-Q1. Each L server has a service that has a local thread pool in which each thread sends a message then calls MessageConsumer.receive() on Q2. All the response messages are queued to L1-Q2 but only half of them are comsumed by the L1 MessageConsumer.receive() threads. The others get consumed by L2-Q2 MessageConsumer.receive(). In the cases when they are not being consumed there is no consumers on L1-Q2 but 5 consumers on L2-Q2. I assumed they should be getting sucked over to L2-Q2. I wonder why they are sometimes. Could you elaborate on you suggested solution a bit? When you suggest using a clustered temporary queue then aren't I losing my persistence on the response message? Maybe I don't need it?
