Re: resource limits
Actually, I have a related question.
We offering web hosting to our clients. When people run huge CGIs, normally
we are notified, and kill them manually. We've also got a small script we
run periodically to kill of any "stuck" or "hanged" processes by users' cgis
(we use suexec so they run under their usernames).
HOWEVER, as this is a reactive measure, rather than a PROactive measure,
we'd rather have a way of LIMITING their usage like we do diskspace.
By putting it in the /etc/init.d/apache script, it would limit the apache
server as well (www-data) user, and thats bad. We ONLY want to limit the
user's cgi processes. We haven't founded any script that suexec uses to run
user cgis, so we can't limit it that way.
Any ideas???
Thanks in advance.
