Somebody in the thread at some point said: >> program results are confirmed with od. > Ox0D is suspecious. This is the carriage return character. How did you He means od, the shell app for "Octal Dump". I don't use NFS, but if this was happening to me I would be looking to add a boring old PCI 10/100 Ethernet card, route everything through that, swap the Ethernet cable with a known-good one: and see if it still happened. The driver for the onboard gigabit Ethernet, or its connection to the PCI bus, can crap on the data before it gets CRC'd for transmission, you wouldn't see any errors on the network interface stats like that. -Andy
