Ahh, I see, yes indeed you are right. One way round may be to have
connections open to each node in the cluster, and watch for when those
connections go down. However, that would require that you know which
node each queue is on. Alternatively, your clients could publish with
the mandatory flag set and then you'll get an exception should the
message not be able to be routed to a queue. Unfortunately, no, the kind
of notification you're looking for isn't available in AMQP.
