In an earlier post I had reported errors on a Tyan 2466 motherboard, 3c905C-tx on-board interface. Donald Becker's response was that I should run the new (9/6/03) version of mii-diag --monitor. Attached below is the output from one of my most persnickety nodes. This covers about two hours of running. The machine is running a normal cpu load plus the "nettest" program which is sending and receiving packets to another node as fast as it can, continuously. Over the course of this test, which is still ongoing, this test generated 33 receive errors in the "err" column of /proc/net/dev, 14 FIFO receive errors, and 29 "frame errors. We did not see any of the messages Oct 3 21:32:37 fnd0196 kernel: eth0: Setting half-duplex based on MII #24 link partner capability of 0000. Oct 3 21:33:37 fnd0196 kernel: eth0: Setting full-duplex based on MII #24 link partner capability of 41e1. during this time. Up to this point I haven't been able to observe one of these errors as it happens, but over the course of this week there has been an average of two or three of them per node in a 240-node cluster. On the remote node I was sending the packets to, there was an error: eth0: Updating statistics failed, disabling stats as an interrupt source. but no increase in the error counters. The down and up messages in the log below follow each other in very rapid succession. The link light appears to blink out but it is very hard to tell. Any advice on what might be happening?
