And the last "consumers" column? How many consumers does the broker
think are subscribed? If the client receives messages asynchronously
then the number should be 1 or greater.
Something else to check is whether the consumer has asserted channel
flow. That will prevent the broker from delivering messages on the
channel. You can confirm this with
"rabbitmqctl list_channels client_flow_blocked"
