The Java client has been supporting (and responding to) channel.flow for 
ages, so I doubt this is a version problem.

Is the client perhaps really busy and thus not getting round to 
responding to the channel.flow in time?

You may want to trace the client-server interaction with the tracer 
(http://www.rabbitmq.com/examples.html#tracer) to check on the sequence 
and timing of the commands.
