File disappears after copy from Mac OS X to Samba 2.2.7

[Ed Holden]

Someone on the regular Samba list suggested that I contact Conrad 
Minshall, so I joined this list.  I'm having a problem when copying 
files from Mac OS X (10.2) to a PPC Linux server running Samba 2.2.7.  I 
can replicate this intermittent problem on an Intel Samba server as 
well, so it's not distro-specific.

The problem is this: some files disappear after a copy from OS X to 
Samba is complete.  A command-line analysis (i.e., typing "ls -l" 
repeatedly) shows that the file really exists and fills up with data 
during the copy, but then it vanishes.

The Mac does some unusual things when it tries to write the file, 
including creating a .DS_Store file, as well as a temporary version of 
the target file beginning with the ._ string.  Still, nothing really 
suspicious.  I suspect that this is an issue with Mac OS X dropping the 
file prematurely, and indeed a Google search reveals that OS X users 
have seen similar problems, but only with Samba shares.  Also, it 
doesn't happen to all files.

I did a level 10 debug on the Samba server and was able to find what I 
think are the last few lines that deal with the upload of a file called 
"gnu-linux.pdf", which I copied to the folder "\NRL Databases" and which 
immediately disappeared.  A snippet is included below, but there are a 
LOT of lines containing opening and closing that file during its copy. 
Does anyone know what I should be looking for in this log, or how to 
correct the problem?

Thanks in advance,
Ed
