Very Computer

I have a copy of apache 1.26 and perl 5.004 running on an RS6000 with
AIX4.21(its a dual 166 with 256mb of ram).

My problem is that under normal load everything is peachy and works
fine, but as soon as the server gets busy Apache won't execute my PERL
CGI scripts and puts the 'Could not spawn child process' in the error
log.

I've tried increasing a few of the usual settings a bit e.g.
MaxKeepAliveRequests 120
MinSpareServers 10
MaxSpareServers 20.
MaxClients 200

This hasn't really worked, do I need to go higher? or is there another
problem? I'm getting the error once I get to about 70,000+ page requests
a day or 60+ child servers running, the server will still dish out flat
files, and will exec cgi's again if I do a graceful restart. Also, the
AIX box is not really stressed out - it's not io or cpu bound.

Any ideas/solutions much appreciated

        List them with "ulimit" (for sh/bash-style shells) or "limit" (for
csh-style).

        On my FreeBSD box, I found I had to increase root's curproc setting
from 64 to a safe value (256). You may need to do the same for the
webserver user.
