The mined directory for both architectures contain temporary files that apparently sftp has left there (they have the suffix SftpXFR.<PID> I think). These should be removed, but maybe the transfer script that moves the files from the upload area could be extended to ignore or delete such files so they never get distributed to the mirrors.
