What happens if you use "cp" or "dd" instead to copy the file
from the client to the server?  There are some very different
code paths that get exercised by the 3, and it would be useful
to know whether it's the explicit write path, the page fault
write path, the explicit read path, the page fault read path,
or some combination of the 4 that result in the error.

Using the 'cp' and 'dd' approach, you would eliminate/implicate
3 of the code paths (given your existing results with 'mv').
