I've had similar problems with my Compaq Proliant 6500 and 5000 series machines running RH 7.3. When I copy
large amounts of data initiating the copy from the destination machine the source often has a problem where
the network cart goes into spasms where on the text console the card is trying to negotiate full / half
duplex. When this happens the only resolution I've found is rebooting the machine. I've tried
/etc/rc.d/rc3.d/S10network stop or restart but it doesn't fix. I have noticed that if I attempt a similar
transfer but start the copy from the source to the destination the NIC locks up much less frequently. I've
tried this on Netgear 10/100 hubs, Linksys 10/100 BEFSR41 switch and a GetNet 8 port switch. The machine I've
had the most trouble with runs the tlan Ethernet driver.
