I also could get back into HiJack. I'd say that whatever you're seeing is also the same thing I am seeing. Now, did you see this without HiJack also? I ran my player nonstop on shuffle for like 15 hours with the b11 consumer image only installed and never had a lockup. Reinstalled HiJack and got two inside of 90 minutes. Interestingly enough too, this seems to happen a lot more on AC power.

** EDIT ** Hmm.. well, I dont think that's my problem. I have port 80 closed. Im going to plug the player in and let it run not connected to the network and see what happens just to satisfy my curiousity.
