My mac change hostname all the time that I reconnect in internet using 3G.
If i drop rabbit without disconnect Rabbit start without problem. If I stop
and start connection between rabbit's start stop, rabbit crash.

But in RHE and Debian environment I don't change the hostname and the
problem is the same, Tomorrow I will try to reproduce it in my servers and
report here.
