Error: "Cannot Close Remote File" uploading files larger then around 100K

2015-12-08 02:28

Using WinSCP Version 5.7.5 (Build 5665)
Protocol: SFTP
Port: 22

Error occurs Uploading file to NetApp server
Error occurs both using WINSCP GUI and command line interface
No errors occur downloading files

File size is relevant to the error:
Files under 10K: Error never occurs
Files 10K – 50K: Error is intermittent, occurring more frequently as the file gets larger.
Files 50K-100K: Error occurs almost all the time
Files > 100K: Error occurs all the time.
Whether the file is uploaded as binary or text is not relevant.

When the WinSCP GUI displays the error window, I click “Abort” and the file transfer operation completes.
The error is associated with the server handling of the SSH_FXP_CLOSE command. The server returns the status message: “no such file”, so the client logs: “Cannot Close Remote File”.
After I click “Abort” to the error, the server returns a directory listing (that includes the uploaded filename) without error.

NOTE: I have turned off temporary file renaming from the client to prevent uploading to a temporary filename and then renaming at the end of the transfer. That was a problem in the past because the FTS server does not allow file renaming.

Here is the relevant part of the log for upload of a 300K file that generated the error
(The log for an upload that generated no error follows this one)
I bolded relevant lines and also translated the HEX status messages – see the lines beginning with “RWINKLER”

(These first 8 lines show the end of the file upload):

After clicking “Abort” to the error, the upload finishes and the file appears on the FTP server with the correct size. When I download the file I am able to verify that the entire file transferred OK.

Re: Error: "Cannot Close Remote File" uploading files larger then around 100K

2015-12-10

The error comes from the server, when WinSCP tries to update file timestamp and/or permissions.

I cannot know why the server fails the request.

Maybe there's some process that takes the file away when the upload finishes or something similar.

In that case, try to disable preserving timestamp/setting permissions.

Hello @martin – thank you for your reply,
I tried your suggestions: "disable preserving timestamp/setting permissions" (please see attached)
and still get the error.
The error does not occur with other clients e.g. CoreFTP.

Hello @martin here is the log file your requested. I unchecked all the "Common options" including "Preserve timestamp" and also unchecked all "Upload Options". I did this for the "Transfer Settings" of all "Presets" i.e. "default", "Text"...etc.
I get the exact same error.
I have attached the entire log from startup of WinSCP to after the file is uploaded.
Below I've pasted a truncated portion of the log from the end of the file upload to after I click "Abort" to the error message and the file finishes uploading.

Sorry, I was wrong. The error comes in a response to closing the uploaded file. You have actually found that yourself, I didn't read your initial post carefully.

As I wrote already, these kind of problems typically occur, when there's some process running on the server that is moving the uploaded files away. Though this typically happens only with operations after closing the file (such as updating file timestamp/permissions, hence my first incorrect analysis).

If the file is moved away before the file is closed, it's simply a bug in the process. The process is possibly triggered by a time interval since file creation. So it happens, if you do not manage to finish uploading the file within the interval. That would explain why it is happening with large files only.

Hello @martin,
Thank you for your last reply. There is no process running on the server that is moving the file. After I acknowledge the error the file finishes uploading and it appears in the folder it was originally uploaded to. We are not having this issue with two other clients CoreFTP and FileZilla, but I would like to continue using WinSCP as we have a lot of time invested in it.

FileZilla ignores errors for SSH_FXP_CLOSE request. So it silently hides away any problems.

This is relevant FileZilla code. Note how the return value of fxp_got_status is not even read in fxp_close_recv.

static int fxp_got_status(struct sftp_packet *pktin)
{
    ...
 
    if (fxp_errtype == SSH_FX_OK)
   return 1;
    else if (fxp_errtype == SSH_FX_EOF)
   return 0;
    else
   return -1;
}
 
void fxp_close_recv(struct sftp_packet *pktin, struct sftp_request *req)
{
    sfree(req);
    fxp_got_status(pktin);
    sftp_pkt_free(pktin);
}

I do not know CoreFTP good enough.

Hello @martin,
Regarding your last reply:

FileZilla ignores errors for SSH_FXP_CLOSE request. So it silently hides away any problems.

I wrote similar code in the wrapper I built for WinSCPnet.dll. The error generates an exception which is caught in the exception handler and then ignored. This works for our automated uploads as the file upload does complete even after the exception.

But there is no workaround, that I can see, for manual uploads using the WinSCP GUI, except to click "Abort" or "Skip" in the error window popup.

Is there a setting in the WinSCP configuration that can be set to bypass this error? If not, would it be a good idea to add one to a future release on WinSCP?

Thanks - Richard

I do not think so. It's clearly a bug in the server. So, it should be fixed on the server.

@zoupie: Sorry, your post does not include enough information.

Please read how to troubleshoot problems with WinSCP. If it turns out that you are not able to help yourself, read how to ask for support or report bugs efficiently, so others can help you.
