I was using almost a half meg file and that puts a big load on the server. I believe though now after looking into my situation, my main problems was the fact I wasnt clearning sessions and leaving threads "stuck".

This would mean that I would possibly have threads still running from who knows how many previous sessions. Well I was running the script 24 hours a day for a over a week. I would imagine that after a week or so all those open threads were causing a really big overload.
