<div dir="ltr">Hi<div><br></div><div>We are running an (admittedly old) rabbitmq cluster pair, both running�<span style="color:rgb(72,72,72);font-family:Verdana,sans-serif;font-size:12px;line-height:17px;text-align:center">2.7.1 / R14B04</span></div>

During this recabling, it looks like both boxes lost network connectivity for a short period (or eth1 became eth0 and vice versa) which caused rabbitmq on both boxes to crash.</span></div>

Both nodes in the cluster are disk nodes so I would have thought the definitions would be stored on disk to be read in in the event of a restart.</span></div>
