I upgraded both the client and the server to the latest kernel, 2.6.1-gentoo, and the problem went away. I was able to write a 20GB file to the server with no errors.
It figures, I spent a week searching the net looking for any answers, trying different configurations with no luck. I reluctantly post the mailing list and magically solve problem the next day. :| Quattro On Mon, 2004-01-12 at 23:32, Steven Marcotte wrote: > I posted this in the Gentoo forums and didn't get much response back, so > I am posting it here.
