On R12B-4, here's the problem:

$ /etc/init.d/rabbitd start

We did it too. But when movinf to R12-B5 we noticed that Rabbit failed to run.
So, we want to come back to R12-B4 with no success.

Something is definitly related to Rabbit Mathias.
All our Erlang apps run perfectly when moving to R12-B5. And they are
running very well when we decide to
fallback to R12-B4.

So?

We did that 2 times today Mathias. Same result on 2 diffrent machines
under Linux :
* Linux Fedora 2.6.18-1.2849.fc6 #1 SMP Fri Nov 10 12:45:28 EST 2006
i686 i686 i386 GNU/Linux
* gcc 4.1.1
* Bi Intel(R) Xeon(TM) CPU 2.80GHz
* 1Go

No other application is running on these two boxes except our Erlang
app's and the expected RabbitMQ.

Any advices?

N.B: I've already send the "erl_crash.dump" last time I reported that.
