known_hosts should contain a comma-separated list of host:port entries, 
including the host:port you are connecting to.

I am not aware if any problems in that area, so if you have a test case 
to reproduce the problem please send it to us. Also, please try running 
the tests through the tracer 
(http://www.rabbitmq.com/examples.html#tracer), to check that the server 
really isn't returning the correct information.

Note that known_hosts has been removed from AMQP in version 0-9-1, so 
you may not want to spend too much time implementing a solution based on 
it. I'd recommend using an out-of-band mechanism instead.
