You might notice that messages are processed through RabbitMQ very slowly. This issue has been seen in a clustered environment, where processing time was acceptable, but then became very slow after other nodes in the cluster were stopped.

The root cause has been tracked to a bug in Spring AMQP. Instead of redirecting messages to the active node, RabbitMQ was incorrectly in a wait state on the stopped node.

After you apply this fix, AMQP version 1.7.7 is replaced by AMQP version 1.7.11.
