I ended up having to reboot the system to get it working again. netstat -nr looked normal. If / when it happens again I will try the other commands you have suggested. It seems like it happens when there is a heavy mail load on the system. I run the SmartList MLM for several mailing lists on here. By sick I mean it's more like it's getting a cold. The TCP/IP traffic starts getting congested and stops flowing. :-) The first time it happened I was out of town on a Boy Scout camping trip with my son. I ended up having to drive back home and mess around with it to get it back up and running again. The second time it happened I was logged into it and could see the gradual degredation happening. Eventually my telnet session dropped and I had to drive home and see what was happening as I could no longer telnet into it. I found the system running happily along with a load of 0. No data was going in or out. Ping gave the error I mentioned above. I was in a hurry to get it fixed so I just rebooted. Everything came up fine. I'm still puzzled by this one. Thanks, Terry Todd
