I would tend to blame the 3c509 for this. I've got tons of problem with them,
because of their really small fifo. Could you try another ethernet
board (ne2000 are good, but a DMA-capable board would be better for
a server).
In a general manner, I now tries to avoid 3com networks adapters (althouh
their other networks products seems good).
