[Samba] smbclient recursive get skips files (rarely)

[David Mathog]

We seem to have stumbled onto an intermittant bug using smbclient
to retrieve files from a W2000 server.  Every so often it just
ignores some files on a recursive mget. When it ignores files
it always ignores the same files.  The exact same command
repeated again may (or may not) pick up that file.  Running a DIR
on the directory in question shows the same defect, sometimes the
cursed file is listed, other times it isn't.

This bug just appeared recently, nothing has changed
on the Windows side.  On the linux side it is running
Mandrake 10.0 and one of the samba updates may have
triggered this.

Any suggestions?  Details follow my signature.

Thanks,

% smbclient -V
Version 3.0.6

(just updated to 3.0.10, and same problem is still present)

The command is like this:

% smbclient '\\3730workstation\E$' -U 'Administrator%thepassword' 
        -D 'AppliedBiosystems\UDC\DataCollection\Data'  -d 4 
-c "prompt ; recurse; mget WEAPON_OF_MASS_DESTRUCTION_2005-02-04_0891
; exit " >/tmp/foo.txt 2>&1

In this case the file:

02_04_05a_G07_zylka_7301_t3.ab1 may or may not transfer.  Here are
some parts of the -d 4 log in an instance where it did NOT transfer:
