I've seen something similar [1] happen to a LAN with one Windows XP machine
running vcool: http://vcool.occludo.net/ . This is also available for Linux
(http://vcool.occludo.net/VC_Linux.html). Are you running this patch or a
similar one?

[1] all machines were seeing frame errors on packets > 250 bytes; it was a
10 mbit coax lan.
