Ejabberd crashes on Fedora 7

Hi all !
My ejabberd server worked well but since I have restarted my ejabberd daemon yesterday after one month of uptime it doesn't start, writing some output to ejabberd/sasl.log. While the
daemon was up I updated erlang to erlang-R12B, but after downgrading it the
problem still occurs.

Here's the log :
