Connection lost to target host

Hi,

I try to transfer an IBM Maintenace level tar.gz file from my Windows host to the target rs6000 machine. The file is about 300MB in size.

After a few seconds the transfer stops and a message box is displayed saying:

Host has not answered for more the 15 seconds. Still waiting ...
Warning: aborting this operation will close connection!

I can only press OK and then the session is lost after sending 40KB or so.

How can I make WinSCP continueing the connection?

What version of WinSCP are you using?

BTW. I'm leaving for one week, so do not expect further answers soon.
