Does it do the same thing when ftp'ing from the LAN? Ours does, which tells me the problem doesn't relate to cdrom file xfers. I applied Alan's suggestion when he passed it on to me and I haven't had a reoccurence, though I haven't tested it hard either... just normal ops. Perhaps I need to test it now to help out with this!
