Fatal Failure with transfer of large files

I am having some trouble transferring large files (~19 MB) without getting a fatal failure error message. I am able to fully transfer smaller files successfully.

I am currently using the latest version of WinSCP, no upgrades. I'm running on a Windows XP OS, version 2002. The transfer protocol is SCP and I am using the GUI commander interface.

After signing in to WinSCP, I type in the directory that contains the .img files on the remote server that I would like to transfer. I click on the 19MB file and drag it over to my local directory on the C drive. The transfer starts to copy and upload to the local directory, but stops about 70,000B into the transfer with the following error:

Error:
Server Unexpectedly closed network connection.
Copying file 'filename.img' fatally failed.
Copying file from remote side failed.

The following is the logging information from the session.

The log goes on to list the current files in the directory.

Is there something else that I can try or some option I can change that will enable the transfer of these larger files?

This does not happen when using 4.1.8
(However, thanks for that fine program)

+1

With 4.1.9 everything works fine, but with 4.2.5 and 4.2.6 from the same server I can't transfer large files. I successfully transfer files of 8 MB, but can't transfer even 16MB, it fails with the error
"Server Unexpectedly closed network connection.
Copying file 'filename.img' fatally failed.
Copying file from remote side failed."
after transferring few bytes.
I tested it on few different servers, all of them running different types of Linux, and in all cases it was just as described above.

Large file transfer fails

I am having the same problem. It worked with the previous version, but the new version won't transfer large files.

When can we expect a new version with the fix?

same problem

I've the same problem with version 4.2.7. All versions since 4.2.0beta have the same problem with larger files. I assume it could be somehow related to the
- Improved flow control with SSH-2, what improved transfer speed, particularly for downloads.
(see version history), which was introduced in version 4.2.0beta? Just an idea... Maybe it helps?

I am facing the same issue.
Could you please let me know the associated bug number.
Have tried searching it in the tracker but no luck.
I have also upgraded to version 4.2.8 build 818 but the issue still persists.

I just ran into this issue today with 4.2.7. I've just tried 4.3.0 and I get the same thing.

I downloaded 4.1.8 and it works fine.

Hi,

something new on that one ?

Were running into the same problem. Tried 4.19 and it works fine. But as you know, language settings dont work with 4.19 on Windows 7 :(

It's a bug in OpenSSH that WinSCP is now triggering... I commented on it here:

Perhaps someone with privileges can add it to the bug tracker?

The workaround is to use version 4.1.9 or switch to sftp mode instead of using scp.
Thanks for your post. This issue has been added to tracker.

Sorry for digging out such an old thread, but... I just tried v4.2.9 and 4.3.6 and the problem still exists! :(
Went for 4.1.9 and this one works well! I'm using Win7 Home Premium.

Only large files are affected... large means >~10MB. I had an 11MB file that failed to go, but an 8MB file went through fine.


The strange thing is, I've been using that 4.2.9 for about 2 years and it has been working fine. Then I had a small problem with my HDD and had to replace it. New windows installation, new everything. And now it doesn't work. But 4.1.9 does!
Maybe it's the windows installation. I had the one ASUS built-into the laptop. And now I have one I downloaded from M$.

Re: Fatal Failure with transfer of large files

I am having some trouble transferring large files (~19 MB) without getting a fatal failure error message. I am able to fully transfer smaller files successfully.

I am currently using the latest version of WinSCP, no upgrades. I'm running on a Windows XP OS, version 2002. The transfer protocol is SCP and I am using the GUI commander interface.

After signing in to WinSCP, I type in the directory that contains the .img files on the remote server that I would like to transfer. I click on the 19MB file and drag it over to my local directory on the C drive. The transfer starts to copy and upload to the local directory, but stops about 70,000B into the transfer with the following error:

Error:
Server Unexpectedly closed network connection.
Copying file 'filename.img' fatally failed.
Copying file from remote side failed.

Is there something else that I can try or some option I can change that will enable the transfer of these larger files?

I don't see this option anywhere in 4.3.7. I have the Advanced Option checkbox selected but when I go to the Connection tab on the left side, I see no "Optimize connection buffer size". Can you be more specific about where this is?

Martin,

Like everyone else, I'm also seeing this problem. If I revert to 4.1.9, everything works fine. Every version I've tried past that has the problem (429, 432, 433, 435, 437).

In the tracker you say that you added an 'Auto' option to the "Optimize connection buffer size" option and that previously 'Off' was required to solve the problem.

I can't seem to find the "Optimize connection buffer size" option anywhere in 4.3.7. Is it hiding somewhere I'm not looking? Another poster, TJ, said to look under Advanced Options | Connection but I don't see it there. Can you give me a pointer to where I can set this option?

I would much prefer to use 4.3.7 instead of 4.1.9 but I need to be able to transfer large files. Any help would be appreciated.

- James

It's available in 5.0.6 beta only. Can you please try it?

YES! I can confirm that WinSCP 5.0.6 (build 2074) WORKS when connecting from Win 7 Enterprise 64-bit to CentOS 4.4 with the "Optimize connection buffer size" option off (unchecked).

I tried it with the "Optimize connection buffer size" option checked and unchecked. When the option is checked (on) WinSCP FAILS to download my test file (85 meg). When the option is unchecked (off) WinSCP WORKS using the same test file. I also confirmed (via md5sum) that the downloaded file is bit-identical with the source.

I don't, however, see an option of "auto" or anything other than on/off (checked / unchecked) for the "Optimize connection buffer size" option. Is that somewhere else or is that an option in a different version?

Thanks,

Re: Can't find "Optimize connection buffer size" option anywhere

Hello,
I tested it also in it worked! Transfer of large files.
But i normally use a batch file to copy my large files.
How can I disable this option "Optimize connection buffer size" in a batch file
The batch file is started like this.
winscp.exe /console /script=c:\scripts\copyfiles_script.txt /log="c:\scripts\copyfiles.log"

Regards
Jeffie

Re: Can't find "Optimize connection buffer size" option anywhere

Can either of you (ideally both) post a log files with and without the Optimize connection buffer size set?

If you do not want to post the log publicly, you may email it to me. You will find my address (if you log in) in my forum profile. Please include link back to this topic in your email. Also note in this topic that you have emailed the log.

Your forum software wont let me post it (I don't know why it wont allow a 4M text post :shock: ) and it isn't worth the hassle to create an account just to get your email address. If you want a copy of the log files you can email me at amFtZXNBVGhtcGdET1RuZXQgDQo= (base64 encoded). I will also try to attach a zip with both files to this post.

Thanks,

- James

Re: Fatal Failure with transfer of large files

I am having some trouble transferring large files (~19 MB) without getting a fatal failure error message. I am able to fully transfer smaller files successfully.

I am currently using the latest version of WinSCP, no upgrades. I'm running on a Windows XP OS, version 2002. The transfer protocol is SCP and I am using the GUI commander interface.

Try running it from the command line, find the WinSCP.com file, it's usually in C:\"Program Files"\WinSCP, so in a Windows Command Prompt window type

C:\"Program Files"\WinSCP\WinSCP.com

And it will give you a winscp prompt

winscp>

From there, it's basically the same as ftp from the command line

winscp>open username@server

After entering your password, use put to transfer a file to the server or get to transfer a file from the server. close closes the connection, and exit gets you out of WinSCP.

I couldn't figure out any way to transfer a 5 GB file through the gui, but it worked like a charm from the command line.

I found a similar problem today transferring a 6 GB file over a LAN. Interestingly it happened with the old version I had installed (version 3 I think) and still with the newest release.

With the optimised buffer size I would get a variety of errors, and with it disabled I get a sustained transfer speed of 3,200 KiB/s or so.

Admin - I'll send some logs to your email address later which I hope will help you fix this bug.

Cheers
