You ran out of swap.

Dear all,
for the first time ever I had one of my production boxes crashing.
And that was just a few hours after I allowed one of my users
ExecCGI in her home, in the chrooted, default, Apache.
The user was deploying some perl-script.
Can anyone with insight please look at the trace and point out to me
if there is a link between the +ExecCGI and the panic?
Was I blue-eyed when I allowed the deployment of perl as a non-
privileged user in the chrooted Apache, thinking that Apache and
perl would handle any exception well enough to not crash?
Thanks for advice,
Uwe
