I went through a 4-6 month period about a year ago with CTDs, they were caused by having dual firewalls (PIX out front Linksys behind it). I am running only on the PIX now and did not have any issues until last night. I dumped while RTB'ing a pony with 8 kills in the bag, I was at about 200 feet over the water, hit WEP (just to get home faster) and POW...CTD. This never happened in the other AH2 builds, and I flew almost every one of them. I am wondering if maybe the server load was part of it, since I'd never flown AH2 with that many people in the arena.
Then again, it was only once, that by itself means nothing.
