Re: Please help: resource limit for running Perl under Apache?

Hi.

It sounds like what you need to do is :
add some logging directly in your perl script, to a separate logfile.
(And maybe re-open STDERR to that same logfile).
Then you will see exactly where and why the perl script crashes under Apache.
Do not forget that when the perl script runs under Apache, it runs under the same user-id 
as the Apache webserver.
