Memory Problem

Hi,

I'm running into some memory problem with this one scrape I'm having.

I have scrape this site 3 months ago and it worked fine.

Now I go to scrape it and it shoots up the memory really high after a couple of minutes.

My specs:
Win 7 ultimate x64
intel i5 760@260ghz
4gb ram
1024mb memory allocation in screen scraper settings

Things I've tried:
Strip the Write Details Script to log the sku only.
turn tidy off
limit size of details page to 1.5mb (it's around 2.5mb original) via scrapeableFile.setMaxResponse();
Tried to run it on a different computer, same thing.
Sometimes it even freezes screen scraper when I run the scrape, and then I have to end screen scraper through the windows task manager

Could I send it in and see if you can replicate the problem?
