Do you see timeouts in rabbit.log on the instance which had many connections during the
incident, on the instance which had almost no connections during the incident, or on both?
How many connections does each broker have right now?
Essentially, I think we can get some useful insight into the problem if we understand why
one node during the incident had no connections and another had all of them (provided this
is not how you guys usually run it).
Also, to confirm info from your original report: you saw the problem was resolved when you
attached a consumer to 2 non-important queues and drained them by consuming all messages
from them. Did you do it on the node with connections or node without connections, and on
which nodes did those queues live?
I know I keep asking basically same things over and over again, just shooting in the dark
