[rabbitmq-discuss] Orphaned channels after connection close in Rabbit 3.1.4

Thu Aug 15 11:14:11 BST 2013

Oops sorry, premature send. In the connections view they don't say blocked,
flow or running. When you click the connection it doesn't have a "state" at
all. However rabbitmqctl list_connections lists them as blocked.

These publishers are still publishing to node A, and again there's no stuck
connections on node B. Both nodes are identical hardware (not VMs), and are
completely fine in terms of resource.
