Large file upload reports successful, but destination has 0 bytes

[Wes Hinsley]

With version 3.1.6, I've had problems uploading a file that is 15,738,880 bytes. Progress bar goes from 0 to 100% in the right kind of time, and the transfer moves into Successful, but the destination file has 0 bytes.

I've tried multiple times, including deleting the 0 byte file. I eventually used standard command-line ftp, which was successful. The ftp server is PureFTPd.

Let me know if I can help more...

Got logs?

I want to confirm this bug.
Mine observation is such that file which has more than 1,5GB have 75% chance that will be 0B at the end of uploading. I have never this bug with file which is smaller and always if file has 1,5GB and more uploading finishing succesfull after 5-6 times of trying.
As I see - it's doesn't matter what FTP server is. I'm using some FTP server on Windows Server 2005. Type of connection: FTPS.
Here is what I can see in filezilla log:
