I'm using prefork apache 2.2 and I can't seem to figure out why there is a MaxClients directive and a ServerLimit directive.
I understand that you need to increase both of these in step -- google has told me this over and over again. As far as I can tell they both control the maximum number of Apache process running at any time.
Why do they both exist? For prefork, they seem redundant. Is there a subtle difference I'm missing?
