Also, are these connections going via some kind of firewall or loadbalancer? If so, perhaps the connections to the server are kept open there.<div class="im"><br></div></blockquote></div><div><br></div><div>To close the loop on this, the problem seems to be solved. We're using a Juniper SSG350M firewall that was configured, according to the network guys, to allow all traffic between the client machine and the server running RabbitMQ. Traffic was going through, obviously but I kept seeing these rather mysterious network glitches between the the client and RabbitMQ. The network guys then explicitly opened port 5672 and the problems went away. Unfortunately, I can't investigate this any further (or confirm the details myself) since the network is managed by another company but hopefully this information will help someone in the future.</div>
