I have also been having this problem.  I run a Lex Systems CV860A with 
Realtek NICs and 256 MB of RAM, 800 MHz processor.  Not using a lot other 
than DHCP and quite a few VLANs and virtual interfaces running on OPT1 and 
some NAT stuff.

My lockups come between 2 and 7 days apart.  Doesn't have to be heavy load. 
I've been watching this thread and don't think this is a NIC issue - my 
boxes (2 out of 5) lock up and I can't even make any input using the locally 
attached keyboard, no response.  Memory issue could be possible.  My 
problems began after I upgraded to 1.2b10.  Whil running 1.2b9 I had uptimes 
of approx. 45 days with no issues.  I just upgraded to 1.2 stable this 
afternoon - we'll see how that goes.
