it may be a memory exhausture. Either bearerbox (by looping in the
re-connection state) or other processes have been consuming to much
memory and the OS would deside on which process to drop silently. Just
an idea.

We have a so called 'safe_wrapper' bash script arround the bearerbox
that acts mainly the same was as 'safe_mysqld' for mysqld. Whenever
bearerbox fails by crashing, the script would create a failure log
directory <timestamp> and 'tail -2000' all logs to that failure log
directory, so admins can at least try to see what has happened.

Usually we have a PANIC in bearerbox that caused to stop. SEGFAULT or
other heavy failures are very rare in the past here at Wapme at least.
