Hi Bruce

64MB and I do admit it's running alot of stuff. However, I have also had 
it running on a 350MHz PII with 96MB of RAM and it still does the same 
thing after around 20 days. I only put the 133MHz machine back to try 
and eliminate any hardware faults.

I think I got a panic message before... dug up from a googling though. 
I've never quite managed to get my head around the whole debugging 
kernel thing. I will try and setup a debugging kernel when this 
buildworld finishes, then wait and see if it panics again.

it wasn't a debugging kernel but from the backtrace of the dump from 
5.2.1-R, for what it is worth, I got:
