Go to /usr/local/etc/apache, and you can see several default files, and one is httpd.conf.default. Give a command like this: cp httpd.conf.default httpd.conf
Of courcse you do this as root. then give a command like this: vi httpd.conf
Look for the item MaxClients and change the number to the number of clients you allow to connect.
