Samba is hosted on a server running Debian-Lenny, on a Reiserfs

After upgrading to 3.3.3, Windows XP clients fail to copy files
through explorer using SMB shares when the file size is around 1.55GB or
greater in size. The error is Cannot copy Filename.ext: The specified
network name is no longer available. Copying existing files located on
the share to the same or any other share fails with the same error.
Copying files from the share to the local client filesystem works
correctly. Linux and Mac clients have no problems. I have not tested
Vista at this point.
The error occurs before any copying begins. The target folder on the
share will contain a correctly-named, 0 byte file after the attempt to
write is made. The POSIX permissions of the 0-byte file on the server
side are correct and the file is owned by the correct user : group.
I do not believe this is related to the error dealing with the
rotation between ports 139 and 445. The copy does not fail after some
time, it is immediate. To be sure, I have tried setting both 445 and 139
alone as the option smb ports = .
Is anyone else seeing this behavior?
Can we see a debug level 10 log of smbd of this problem?
Thanks,
Volker
The logfiles on the Samba server are split by username/hostname. Here is a
client logfile of an attempt to copy a 2GB file to an empty folder the share
( \\shareserver\Sambatest\2GBtestfile.largetest ). The included portion of
the log is about half of the section referring to the file copy, the full
portion is too big for the mailing list. There is also an smbd logfile,
which contains only the statement getpeername failed. Error was Transport
endpoint is not connected repeated. The series of events for this copy
compared to a successful copy seem quite different.
