 I solved the problem. My OS (OSF/1 3.2) is a very old build, so it wasn't
 well configured to run as a web server. So, you have to change your machine 
 kernel configurations, it has a limit on the number of proccesses and the
 number of children that can be spawned, the variables are maxusers (which
 has nothing to do with actual users but the number of proccesses allowed)
 and maxuprc. They were at 128 and 64 respectively, but I changed them to
 128 and 256 respectively. Once you change those configs (in 
 /sys/conf/the_name_of_your_machine) you must re-build the kernel and
 replace the new kernal with the old, of course make a backup of your
 old kernal in case all else fails.
 I haven't seen the error once since rebuilding the kernel, about 15 hours
 ago. The error use to occur at least once every minute.
 Thanks for trying to help anyway.
