The problem turned out to be a bad network card, we replaced it and the problem went away. We also had a problem with corrupted packets on the 100BaseT network around the same time and traced the problem to an early-revision Intel 100baseT hub. According to Intel, there is a known problem with their earlier 100BaseT hubs corrupting packets under heavy load. This same model hub is still being sold by Bay Networks. Sites that have standardized on a single vendor (Intel) for their hubs and adapter cards should test for errors on 100BaseT networks under heavy load. Intel also recommends checking cabling on all 100BaseT installations - pins 2 and 6 should be twisted together on UTP used for 100BaseT.
