I'm having trouble understanding exactly what problem you're describing. 
However, one thing leaps out at me: you've managed to (accidentally) make some of the queues used internally by federated exchanges
*themselves* be federated with each other. This is likely to lead to odd behaviour. I can't guarantee that this is the problem you're describing, but it's certainly *a* problem.

You can either:

a) Rework your policies so that no policy which matches queues beginning with "^federation:" enables federation. (The policy "federation enabled" 
in the vhosts ControlCenter, MediaManager and Review could be changed to apply to "exchanges" rather than "all")

or

b) Upgrade to RabbitMQ 3.2.3, which prevents this confusing and unhelpful behaviour from happening.

Cheers, Simon
