I have limited the number of FreeBSD machines at work because I always feared this would happen. I have a production FreeBSD stable (lat built about 2 weeks ago) which is freezing. Upon freezen the machine would not respond to the keyboard neither I would be able to ssh to the machine. After it froze the first time I booted up single user mode and did a fsck. Some errors were found and corrected. Checked the space to make sure it was not full. It had plenty of space on all mount points. Left the machine working, it is a samba server lightly used, and it froze again after a while (seemed like 30 minutes). The third time around I left the machine running X with "top", "systat -io" and running "make buildworld" running to see if when it froze to see if I could see something which would help troubleshoot. The machine froze again and I didn't see any obvious problems. How does one troubleshoot a freezing machine? Tomorrow I plan to run a hardware check program, tufftest, to see if it finds anything wrong. Other than that I can't think of anything else to try. The machine is on an internal network and only runs nfs, ssh, PostgreSQL and Samba 2.0.10. Given this configuration I am NOT considering this as a possible attack.
