The default location of the cluster config file is
/etc/rabbitmq/cluster.config. The docs say
/etc/rabbitmq/rabbitmq_cluster.config, which is wrong.
Did you change that setting to point to /etc/rabbitmq/rabbitmq_cluster.conf?
If not that would explain why getKnownHosts returns one node only,
though it doesn't explain why it would only do that for 1.5.4 and not
1.5.3. Perhaps your config changed?
To check whether the clustering is set up correctly, run "rabbitmqctl
status". That should show both nodes as running.

I can indeed reproduce your findings: bindings to durable queues
residing on nodes in a cluster are not restored when the queues' nodes
restart. Thanks for reporting this; I have filed a bug.
This happens for me in both 1.5.3 and 1.5.4; the reason that it works
for you in 1.5.4 is probably the same reason that getKnownHosts returns
just one node, namely that the clustering was not set up correctly when
you ran that test.
