[rabbitmq-discuss] PossibleAuthenticationFailureException intermittent

PossibleAuthenticationFailureException just means "the server closed the 
connection unexpectedly during AMQP handshake". It's required to do that 
in the case of authentication failure, but there can be other reasons, 
hence the name.

Check the server logs at the time the error occurs, more detail should 
be logged there.

Cheers, Simon
