Hi
i use my SS20 box as my NAT-router and discovered last night, that it 
crash on high network traffic. It's more or less reproducible with an
nmap scan  from my private network to the www. I had this panic several 
times, but it's the first time i got it while i had a serial connection.
Sometimes there is also a ping cpu warning after the NMI before 
crashing. I think i have this error too with 2x SuperSparcsII, but i 
have to verify.

Best Regards
