Had this happen 3 or 4 times since last posting, tried a few things on my own and nothing seemed to stop the random crash. I've just now set the cache to 50 megs, will report if that makes an improvement.
mmh i can only think of something wrong with your os installation, or maybe your cpu is at 100% when you run the client?
The cpu is idle when this happens, it happens during the day when I am away at work.
I chalk it up to my old computers, if I get motivated enough I'll try the Linux partition, or I may just do nothing until I eventually build a new computer.
