If the problem can only be reproduced over the WAN then I strongly
suspect the problem is with the WAN. Unless there is any AMQP-specific
configuration you should be able to reproduce the problem with other
protocols.

The RabbitMQ server uses sockets in the same way as any application.
(Nagle is turned off by default). The connection teardown is done by the
TCP stack as implemented in your OS. If there is something that you
believe RabbitMQ should be doing differently then let us know.
