Hi Chris, We do Active/Active RabbitMQ with mirrored queues and Precise/Havana. We faced a lot of failover problems where clients weren't figuring out that their connections were dead. The TCP keepalives mentioned in the following bug seemed to help a lot. https://bugs.launchpad.net/nova/+bug/856764 The moral of our story is to make sure you are monitoring the sanity of your agents.
