Re: [cgiwrap-users] rlimit nproc

Um, I can't get that to work in RedHat Linux, Nathan.  There is ulimit,
but it is set to 'unlimited' by default, which is how my server is
setup.

To expand on my original question, I want my server unlimited on the
number of CGIs it can process.  I don't care if it slows down to a
snail's pace, I want them ALL to run when called.

So, by *NOT* including the --with-rlimit-nproc=XX switch, am I allowing
an unlimited number of scripts to be run by CGIWrap?  I looked in the
configure.h file, but it just seemed to be undefined, as Tuc pointed
out.  I'm hoping undefined = unlimited.  :)
