Thanks for your very detailed message. Could you try to enable
heartbeats for the RabbitMQ channels that are established for WCF? The
internal RabbitMQTransportBindingElement.ConnectionFactory() method
looks like the correct place to add this. AMQP heartbeats will probably
help if a network device is causing long-lived connections to drop
silently and peers are unaware of this.

The ghost queues are a consequence of declaring the internal WCF queues
as durable. It seldom makes sense to declare server-named queues as
durable, unless the name is recorded somewhere.
