It seems that after about 45-60 minutes the network interface goes down for incoming traffic only. The device stays down anywhere from 3-10 minutes, then comes back up like nothing has ever happened. We are currently using the 2.4.20 kernel (expieranceing the same issues on 2.4.18) have reinstalled the operating system (debian), replaced network cards (intel, netgear, realtek) and even the motherboard... all to no avail. One shimmering glimpse of light seems to have occured when we disabled tiny packets from entering the network. All other irrevelant services have been disabled probably taking care of any DoS. The server has plenty of processor power and memory to handle the task. Any help would be appreciated. Thanks.
