I suggest you do a 'rabbitmqctl list_connections peer_address peer_port
state channels send_pend' on all the brokers to check that you have the
connections and number of channels you expect to see and that there
is no send backlog (that's what the send_pend count
shows).

Getting a stack trace of all the Java threads at that point might
provide some clues as to why things are stuck.

That's perfectly ok.
