I've got a machine that has been suddenly rebooting. I can make it crash
at will by bringing the load to about 200 with the script below. My other
single CPU boxes can handle a this script with 3000 primes instances just
fine with 512MB of RAM.
Here is what I get whe it goes down. What does it mean?
bash-2.05# panic: vm_fault: fault on nofault entry, addr: cbbd3000
mp_lock = 01000002; cpuid = 1; lapic.id = 00000000
boot() called on cpu#1
syncing disks... 15
done
Uptime: 5m13s
Automatic reboot in 15 seconds - press a key on the console to abort
