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?
