Dejan, The problem was a subscriber to a queue that had set a client-id and subscription-id. Non-persistent messages to the queue would flow across to this subscriber absolutely fine despite there being lots of cast errors present in the AMQ logs.
Soon as I added a new producer that added persistent messages to the same queue, those persistent messages would not shift from that broker which puzzled me. I found the warnings about the subscriber and fixed the code. However, only after restarting all brokers concerned would the persistent messages flow across brokers. As of result of this experience it would be my advice to give a more human-readable error in the AMQ logs when this "Durable topic subscriber" subscribes to a queue, allowing development staff to more quickly realise the problem and get it fixed. I hope this is helpful.
