I receive this message, and the transfer starts over again. Can you tell me what it means?

I believe it is a server problem, but I would like to be knowledgeable about this message when I talk to the server admin.

What version of WinSCP are you using?

This issue is being tracked here.

Can you provide me your email address, so I can send you a debug version of WinSCP to track the problem further? If you do not want to post the address here, you can send me an email. You will find it (if you log in) in my forum profile. Thanks.

Sorry! <removed>, www.genisys-gmbh.com.

I'm getting a similar issue downloading large files.

At the end of the transfer, it pops a timeout error. If I click abort button at this point, the file is perfectly fine. If I miss my 5 second window, it restarts again and again and again.

Currently retrying with debug 1 log turned on.

Here's the tail end of the log...

What I note here is that TransferSocket.cpp(1179): Close() is called 3 times, the last being from the ~CTransferSocket(). I'd suspect the 'timeout' is because you are trying to close a connection in the destructor that you have already closed (twice).

What FTP server are you using? Have you read problem description in tracker? Does it match?

I don't manage the server, but when I connect using the windows command-line client, it reports: WS_FTP Server 6.0 (14829293) I've seen a similar issue connecting to Microsoft's (Windows XP/SP2).

In every case I've observed, if I can abort before the retry starts, the file is exactly what it should be.

I won't say the tracker issue is a perfect match, but it's pretty close.

I have sent you a debug version.

Got the debug version, and it's still not able to complete a large download w/o intervention.

I've captured new logs if you want them, but I deleted your email (or just can't find it) so I can't send them.

.zip is about 36k

See my profile (you have to login).

Thanks,

After a few downloads I realized that the debug version you sent is even worse than 4.0.7. With 4.0.7, the transfer was completed and buffers were flushed to disk before the timeout occured. With your debug version, the file transfer was aborted before being complete.

The results is that WinSCP is now 100% usless to me, instead of 75%. I'm sorry but I have to move on to a different application.

I sincerely appreciate your efforts to fix the issues, but I need to get my work done, and can't spare any more time.

Thank you.

I have the exact same error. It appears to be random as well, WinSCP was working fine for awhile, then this morning I came to the computer and it appeared it was trying to download the same file the 2,000th time because of this bug.

What happens is the file completes then I get the same timeouts and it trys again, and again, and again...

What if your FTP server?

Did anyone managed to get a solution for this problem?
I started experiencing the same issue beginning this week. Previously there was no problems with the same script.
After 100% file download, I get a message "Lost Connection". The connection auto-reconnects and the same file is being downloaded again.
Any help will be much appreciated.

Thanks

Hi,
The problem still there, I have old windows xp64 bit, winCSP version 5.9.2 (build6958), all the symptoms as described

Can you upload a file using any other FTP client?
