FORBIDDEN ERROR -- Help!
Hello,
I had been doing some benchmark testing with ApacheBench to compare the
performance differences between mod_cgi and mod_perl and they were going
great until all of the sudden my results fell way out of line. I need
help! After I switched the max requests per child from 1 to 5000 the
trouble began. Ever since my results have been around 1100 requests per
second. Being so adamant in testing, I neglected in stepping back and
simplifying the issue. After trying to run a script from Netscape, I
got the following familiar error. I have an excerpt from my error_log
when things went bad. I have checked my permissions like the Apache FAQ
recommends but they look fine. Not sure what to do. I really
appreciate the help guys.

Forbidden Error -- more info
Posted by "Richard M. Lemanski" <rl...@ee.siue.edu>.
Hello all,
I have re-checked my permissions in /home/httpd and both the mod_cgi and
mod_perl directories and everything within is set to 755 root root so
there should not be a problem. There is one thing that I recently noticed
and maybe has something to do with this error. When I 'httpd -l' I get:
Compiled-in modules:
http_core.c
mod_so.c
suexec: disabled; invalid wrapper /usr/sbin/suexec
What do you think? Would this have anything to do with the Forbidden
error? Thanks.
