Hi everybody,

as discussed on IRC, we had a crash with our active/active setup. We have two servers, rabbit01 and rabbit02, both disk nodes. Our queues are all durable and mirrored. All messages have the X-HA-Policy of "all". We use haproxy as a load balancer.

Unfortunately I was not able to reproduce the crash. A little context as a long shot: we were deploying a new version of our software. Our deployment process does queue housekeeping (creating queues and exchanges, adding routing keys). During the deployment at least one consumer was running that processed messages. The consumer does the usual read, accept/reject pattern.

Our application log messages (not sure if that is helpful): http://pastebin.com/DrQwKuwL

Best regards,
