I've read that "file size mismatch" error is due to the FTP server limitation, but in this case (I'm using wzdftpd 0.83) a larger file seems to resume without any issue. I've also changed the default action to Resume since the 2gb file has been overwriting itself in a loop for a couple of days now. Kindly advise

Here's my system info:

As you can see from the 2gb log it looks like a a bug with the server. It just does not return any data:

Ah.. Guess I'll forward this thread to the developers. Thanks again
