I have recently installed freebsd2.0 from the Walnut Creek cdrom. While in general the install went well and I am very happy with the system, I do have the following intermittent problem. After a fresh boot and using the system for 10-20 minutes, whatever program I am using will die with errno 11, then shortly the entire system will croak with a message on the console only: Fatal: page fault in kernel mode 15 lines of other interesting-looking stuff stays on screen for 15 seconds then system reboots Programs which have caused the error include: cc1, gm4, make, emacs and others. After a reboot, I can re-execute the same program and not have any problems for a while. If the system sits around all night without doing anything it is fine. It seems that heavy use triggers the problem. I was hoping that with the small amount of information above (I am giving more details below), someone could point me in a general direction of things I could try to do to fix my problem. A reference to a body of knowledge on the net which I could search would be wonderful.
