Comment 13 for bug 1300507

Same here on another machine. Rabbit was full of these:
=ERROR REPORT==== 12-Aug-2014::19:18:59 ===
closing AMQP connection <0.4488.0> (10.96.0.10:36895 -> 10.96.0.10:5672):
{handshake_error,starting,0,
                 {amqp_error,access_refused,
                             "AMQPLAIN login refused: user 'maas_workers' - invalid credentials",
                             'connection.start_ok'}}

And celery.log was full of these:
[2014-08-12 19:06:55,739: ERROR/MainProcess] consumer: Cannot connect to amqp://maas_workers@10.96.0.10:5672//maas_workers: [Errno 104] Connection reset by peer.
