samba - May 1999 - Samba 2.0.4b Error reading file on 100bt only it seems...

Having a strange problem.
Running smbclient to an NT4 Sp4 workstation for testing.
using tar c /some/local/dir
using the default config except for machine name and workgroup in
smb.conf
I've tried tweaking the smb.conf to no avail.
running on Redhat 6.0, but using samba 2.0.4b for the large filesystem
patch...
running on 100bt switched with 3c905B 100bt cards on both ends, but
problem occurs to other 100bt systems as well.
This is a FAT filesystem (no security) and no files are in use.
It happens on every 100bt NT machine I try it on at different levels of
load.

The problem does not occur if the machine making query's is slowed down
sufficiently.  If you turn on debug level 5 or higher, the problem does
not occur due to the speed drop!  I'm using this for amanda, so this is
not a viable option.  Any takers?

Thanks
