[Samba] Samba 2.2.6 Write Problem

Hi all,
recently I asked for help with a problem Samba had to write files
(http://lists.samba.org/pipermail/samba/2002-November/085003.html,
http://lists.samba.org/pipermail/samba/2002-November/085083.html).
Since that hasn't solved, and since it occurs regardless of changes
of the smb.conf, I'd like to post some passages of the smb log file
(log level 4) of the attempt to copy a file to a share mounted
locally by smbmount (which was quitted with an input/output error).
I hope it is not too much log text, but I do not know what could
be important.
The mounts were t that time ::
ufa at chlorine:~> mount
/dev/hda2 on / type reiserfs (rw)
proc on /proc type proc (rw)
devpts on /dev/pts type devpts (rw)
/dev/user/data_vol on /home type reiserfs (rw)
/dev/var/var_vol on /var type reiserfs (rw)
shmfs on /dev/shm type shm (rw)
usbdevfs on /proc/bus/usb type usbdevfs (rw)
//chlorine/homes on /mnt/pdc type smbfs (0)
ufa at chlorine:~>
The command was
chlorine:/etc/samba # cp smb.conf /mnt/pdc
(executed with uid 0)
The original file:
-rw-r--r-- 1 root root 11659 Nov 22 09:18 smb.conf
After that there was an empty file smb.conf in /home/ufa:
chlorine:/home/ufa # ls -l smb.conf
-rw-r--r-- 1 ufa users 0 Nov 22 09:23 smb.conf
The directory /home/ufa was writeable for ufa:
chlorine:/home/ufa # ls -al
total 633
drwxr-xr-x 7 ufa users 896 Nov 22 09:20 .

If someone (I think especially of those with some glue to the
source code) knows what could be causing the
smbd/error.c:error_packet(126) messages and how to overcome that I would
be glad to hear about.
Many thanx
