Fedora forgetting network configurations

[lsuperguy]

I have a linux server running fedora 3 and it has one wired ethernet card.

I have eth0 setup so that it gets an IP address via my DHCP server and I have eth0:0 setup so that it uses a static IP that I assigned. They both have config files in the /etc/sysconfig/network-scripts directory.

Most of the time both addresses work fine. But leaving the machine alone for a while I will come back, or try to shell into the eth0:0 IP and it will not work. I will get in via the other port and when I run "ifconfig" it shows no eth0:0 running. (During this time the eth0 configuration always works fine. )

To get it back I just run "ifup eth0:0" and then it works fine for a while until this all starts to happen again. Right now I'm solving the problem by running a cron job to start up the eth0:0 every 2 hours, but this is clearly not how I would prefer to solve this problem. Does any one have any idea why this could happen? Is my ethernet card going bad?

Thanks.

That's an odd problem. Does eth0 lose it's IP as well? Do you see anything about it in your /var/log/messages?

Nope, eth0 (using DHCP) is always up and with the same address.

I see a lot of DHCPRECQUESTs for eth0 but nothing that pertains to eth0:0.

I tried inserting and setting up a second ethernet card. This will be a test to see if it drops out like the eth0:0 i set up before.

...unless anyone has a clue what is causing this problem?!
