From what I understand Comcast is no longer throttling but they do have a 250GB total transfer cap. If you go over that cap they might send you an abuse notice/warning not to do it again or they will disconnect your cable service.
It sounds like however something has recently changed causing the disconnects possibly your modem or router overheating with 500 or more peer connections. That's a lot of connections and most consumer grade equipment cant handle that much without hickups. I think the norm is about 250 or so max. Ive lowering your max torrent connections a try first to see if it doesn't resolve the issue. Otherwise something else might be going on there.--
