Crashes...

Hello all, Well, sometimes I forget something important to a loop like an increment and when it occurs, my server get crashed to PHP scripts. A few minutes ago I was writing a script and I forgot to put an $i++ at its end. Well the loop gone infinitely, I stopped the execution and when I tried again I've got an infinite "Waiting For Reply..." message. If I try to access the rest of the site normally, like http://mysite.com/home.htm everything goes well like anyother stuff. But when I try even a stupid "Hello WOrld" script with PHP it doesn't answer. Would this be something to correct??? I'm running Netscape Enterprise Server 3.63 with PHP 4.03p1. Thanks... William
