Copied file vanishes when client is OS X

[Ed Holden]

I'm having a problem when copying some files from Mac OS X (10.2) to a 
PPC Linux server running Samba 2.2.7.  I can duplicate the problem on an 
Intel Samba server as well, so it's not distro-specific.  The problem is 
that some files disappear after being copied from OS X to the Samba 
server.  A command-line analysis (i.e., typing "ls -l" repeatedly) shows 
that the file really does copy, and fills up with data during the copy. 
  When it is finished copying 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 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 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 mentioning the opening and closing of that file during its 
copy. Does anyone know what I should be looking for, or how to correct 
the problem?

Thanks in advance,
Ed
