You can limit the maximum number of child processes the apache server can start and also the maximum and minimum number of spare child processes in the httpd.conf file or for SuSE in the server-tuning.conf file in /etc/apache2/
The exact variables differ depending on whether you're using the prefork, worker, leader, metux or perchild MPMs. Also look at your keepalive settings. You may also want to look at your acess.log file to see if you're simply not getting an attack on yours erver by some particular clients trying to overload it. As for perl processes, have you looked through your CGIs to ensure you are not being exploited in some way? Noah.
