That indicates that, for whatever reason, the client is not accepting 
any more messages.

What version of the RabbitMQ server are you running? If it's >= 2.5.0, 
please run 'rabbitmqctl report > server_report.txt' and send us the 
output. Preferably when it's stuck while consuming messages without 
acks, since that scenario has the fewest places to get stuck. If your 
server version is < 2.5.0 then please upgrade.
