This box is the firewall gateway for a internal network ep0 is the outside
interface to the cable modem. It goes to a 100M switch and shares the modem
with two other servers. I've never had it lock with internet traffic, but
sometimes if I mount it nfs to one of the other boxes to do a portupgrade
etc, it locks up. I can't get the box to do it all the time. The other cards
were all 100Mb, same problem. I was thinking the switch, but I tried a cross
cable between boxes and it did the same thing. It's something in this server.
I'll check netstat -m next time it does it. Are there any tweaks I can do if
it is running out of memory?
