Are you restarting both nodes or just one? And when you are "restarting
rabbit", are you just restarting the rabbitmq server process or
rebooting the entire machine?

We filed a bug back in 2009 to come up with something better than the 30
second timeout. But until now we've had no evidence that it is actually
causing problems. Yes, users have been reporting rabbit failing to start
with a timeout_waiting_for_tables error, but in all cases I recall the
underlying problem wasn't the timeout duration, i.e. increasing the
timeout would simply have led to waiting for longer and then still failing.
So another thing to try would be to increase the timeout in the code and
see whether that changes the behaviour you are seeing or merely delays
