Exactly nothing.

Testing on an instance that’s currently using 5.9Gb before I restart it:

 - Nothing logged
 - No change in memory use in the management console.

On the off chance, I also tried stopping and starting rabbitmq_federation, and similarly saw no changes.

I then restarted rabbitmq_stomp, and bingo - memory use has dropped to 225Mb (at the penalty of having bounced ~400 clients).

So I assume that this indicates the STOMP adaptor is somehow leaking memory?
