I experienced the problem every 24-36hrs around five times in a row last week. Pretty much every morning, I'd come in and the box was completly dead. It seems to be okay at the moment, but I'm not holding my breath. > One factoid that I forgot to mention there is that when it happens on my > laptop, the disk activity light is stuck on. My box doesn't have a light, but what I got from SNMP before the box died suggested that the system (e.g. the 'system' CPU usage MIB) was using a considerable amount of CPU time (>95%), so I'm not sure if it was swapping madly, or if something else was going on.
