[TriLUG] Sun Ultra 5 freezes under load

[Jack Hill]

Hi all,

This might be a long shot, but I'm not sure if the problem is specific to 
the exotic hardware.

When the machine is under CPU load it will freeze (sending a break over 
the serial console won't even bring up the openboot prompt) after about an 
hour. 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).

Suggestions on what is going on/what I might do to figure out what's going 
on?

Jack
