I think you may have happened across a bug others have seen before; are
you running .NET on a Microsoft operating system? If so, it is likely
that the Heartbeat feature will not work well for you, and you should
disable heartbeats by setting the heartbeat interval to zero.

See

A future release of the RabbitMQ .NET client will employ an alternative
strategy for detecting idle sockets that does not fall foul of
Microsoft's broken read-timeout behaviour.

Great! Pleased to hear it.

I'd be surprised if you were seeing anything other than the
heartbeat-timeout problem.
