That definitely shouldn't happen, and indeed it can't - there is no code 
in the server that would alternate between queues when handling a publish.

Are you sure your consumers are consuming off different queues?

It might be helpful to hook up your code to the tracer - 
http://www.rabbitmq.com/examples.html#tracer. That will tell you exactly 
what commands are sent at the protocol level.

Also, can you post the complete code?
