Tip: Never try to program at 2 AM when plastered. It just doesn't work.
I'd just like to point out, if something is poorly coded whether it be using perl, c/c++, asp*cough-crap-cough*, or php, it will increase the load time. So there is a possibility that you have a script that eats away at the memory. Or maybe your server just has problems with setup/memory leak.
