[TriLUG] Sun Ultra 5 freezes under load

[Ron Kelley]

Check to see if the CPU fan is running and/or the machine is overheating.    It could also signal a power-supply "on its way out".

What type of CPU workload are you doing?  Anything I/O intensive as well?

The problem seems to be specific to the installation (i.e. not a hardware problem) because I don't see this when it's booted with the livecd. Also, it seems to be specific to CPU usage and not disk usage. I'm not seeing anything interesting in the logs (probably because it crashes before it can write anything).
