It's not just BitTorrent, it's P2P in general. In fact, it happens with ANYTHING that uses a lot of connections. DWKnight had problems since he ran a tracker on his, and after putting in the start-up script into the firmware, it worked great. Anyway, since there's SO many of these routers about, I thought it warranted making a sticky and mention in the FAQ, considering the severe problems the default firmware causes.
