I suspect that if rabbit ran out of processes before the restart then it 
may have corrupted mnesia.

That just means the server couldn't find the exchange during a 
basic.publish, which isn't surprising if mnesia is playing up.

The most promising route of investigation is probably to look at what 
processes are running before the system actually runs out of them.
