I've got a fully-patched wonderfully working FC2 machine. I wanted to change my DNS settings and so fired up the network GUI, system-network-config, made my changes there and then saved. But my CPU meter spiked and wouldn't come down. I waited for over 3 minutes and it still stayed at 100%. It never did save my settings before I killed things manually. I tried this twice with the same results both times. I can't imagine that there's some secret about using the network GUI. I thought I'd post here to see if anyone knows anything about this before I go in and change DNS settings the old fashioned way. Thanks for any feedback!
