Are you by any chance talking about $SIG{__DIE__} hook I added?
(see bottom of src/lib/Site.pm)  This hook is called anytime
process is dying (either by "die" or by "croak"), does some extra
works, and then really dies.

On current Sympa-6.2, dying processes output traceback to STDERR
and (if possible) to syslog.  I believe debugging of the sudden
deaths will be made easier.
