Can you configure a `ProxyLog`, and provide the messages from that log file, for a session which encounters these issues, please?

Thanks. Would it be possible to also get the [ProFTPD debug logging](http://www.proftpd.org/docs/howto/Debugging.html), debug level 10, from the proxy, when this happens? I have a suspicion of what's happening, and am...

Can you run the command-line `ftp` client, on the host on which `mod_proxy` is running, and successfully do several FTP directory listings from the backend FTP server? The goal with...
