BestSync/FTP Problems: 426 Connection closed...

[mcjathan]

I have a long-standing problem with BestSync and FTP. FYI, my FTP server is Filezilla.

An example of the BestSync log is at the bottom of this posting.

At first I thought it was a problem with the FileZilla FTP server and I asked for support on the FileZilla support forum. However, after some back-and-forth discussion with Filezilla developers on that forum, I’m convinced the problem is with BestSync. For more details, please see the FileZilla forum thread:

https://forum.filezilla-project.org/vie ... =2&t=29403

Here’s the most relevant portion of that thread. Please be sure to read from this point down to the bottom of the thread:

https://forum.filezilla-project.org/vie ... 03#p109715

One of the FileZilla developers thinks that BestSync has some sort of an error in its FTP receive loop.

Jean-Pierre, can you reproduce this error?

Regards,

Jeff

Hello,

I think that this symptom only happens when BestSync download ONE large file by multiple threads.

If number of the download files is larger than the number of threads, BestSync uses one thread for one file; when the number of threads is larger than number of the download files, BestSync divide the large file into segments and download load the segments concurrently by multiple sessions. The is the powerful point of BestSync, may be not other synchronization software can do this job.
Please post may answer to the FileZilla forum.

Best regard.
