Hi Steve,
I'm sorry if the patch didn't work out, so let's fall back to the
original plan.

I need you to provide a very detailed debugging log of the events from
when the file is closed after writing, to when iozone says its attempt
to read failed. I want to see all of the system calls and returns, and
the debugging reports of all smbfs routines, if any. (If it truly isn't
making any calls back into the smbfs code, then the problem must lie
elsewhere.)

I'm assuming only that the Win 3.1 server is somehow different, as the
smbfs code works fine when talking to Win NT.

Regards,
Bill
