That probably is the problem.

You have two connections that concurrently upload files.
On the server side, there will be two threads processing the
requests. If the files go to the same folder, there may well
be a conflict for the common folder.

The only strange thing is, that you get told that
a conflict occured for "/em/nav/aiti2.gif" rather
than the folder.

You are sure, your FTP client works correct and does not
try to upload the same file via two connections?

Anyway, folder conflicts are to be expected.
Can you tell your FTP client not to serve several
connections concurrently?
