Subject: Re: lost response while transfering large file to FTP server

Thanks for reply.
I didn't create a new thread to do the ftp job; it's in main thread. I 
think any exception will be throw to the console, but nothing happened. 
And the file was actually transferred without any error I am aware of. 
ftp.put just couldn't return.

I attach the source file.
