This is an upgraded gigabit ethernet G4 - 100 MHz memory bus, 1.4 GHz 
accelerator, 2 gigs of memory, NetBSD 2.0. It was serving anywhere from 
5-10 Mbps of traffic and getting about 30-40 Mbps of DDoS traffic at the 
time.

It's usually a pretty busy server, but the crashes have been so 
infrequent that I am having a hard time finding any correlation with 
what's going on. I'd love to figure it out, though.

I'm half tempted to move everything back to my 400 MHz 604ev 9600, since 
that's been up for 1/2 a year, served more than 5 TB, done several bulk 
builds, and hasn't crashed at all since I removed awacs from the kernel 
config...
