I saw something similar once... we have an 8 core fibre running from the server room to the middle of the site, which then goes to separate buildings. A cabler accidentally patched two pairs of the same gigabit switch together, so there were a lot of packets going round in circles! The interesting upshot is that 95% of the NT machines on the network bluescreened, whereas the printers and linux boxes were okay.
