Hi, We've got 200 nodes running, with each node having a Biostar MB with a built-in Realtek 8192 NIC chip, and running RH 7.2, 2.4-17. Recently we've seen a weird problem with the network connection to some of these nodes. About 20 of them will lose their network connections during the course of a few hours to a few days. And if I just unplug the network cable from such a node and plug it back in right away, the connection will come back up. Any insight where we should look for the problem: hardware? BIOS? Driver module? Such a problem does not happen to any nodes randomly. It only occurs to those 20 or so particular nodes, which are identical to others except their MAC addrs. Thanks. Yudong Tian
