Huge ftp file uploads stop an 100%

Yup, I found someone had similar problem, but there was no solution for this. This makes the ftp queue useless any ideas how to fix this? maybe there is a plugin to use external ftp client or download manager?

This happens when the FTP server control connection is disconnected during the upload, e.g. by a firewall. The control connection is the connection used to send commands to the server. Currently there is no workaround to this problem, sorry.
