[rabbitmq-discuss] HA queue disappears when a node rejoins the cluster

Tue Aug 28 19:12:19 BST 2012

Just pinging this thread as it seems to have gone dead, and it feels like a
serious issue with clustering/HA in 2.8.6.

When we last left off, Matthias had asked for the logs for the two other
brokers when the queue disappeared. My last message contained the contents
of those logs.

Thanks,

Matt
