I have not been able to reproduce this problem outside of our application,
but I'm still trying.
Anyway, I'm using regular Kaha persistence (not AMQMessageStore), and during
a Durable Topic test, I'm eventually getting the following exception in the
AMQBroker, after which the broker stops forwarding events to the consumer.
Anyone seen this?
