I had those problems too a while ago on a UP p3-650 laptop. Finally I just newfs'ed the machine and installed the 20001028 snapshot, then cvsupp'ed to 20001122. The laptop now works well. What I saw was processes forking and forking again until the machine runs out of memory and swap. I think it may be some old libraries left over from upgrades and make world. -- +------------------------------------------------------------------+ | keichii@peorth.iteration.net | keichii@bsdconspiracy.net | | http://peorth.iteration.net/~keichii | Yes, BSD is a conspiracy. | +------------------------------------------------------------------+ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
