Martin,
Thank you for your response, I was able to determine the issue was related to the disk quota for the uploads directory on the sftp server.
I contacted the administrator and requested an increase of allocated space and the uploads were able to be completed successfully.
It may be useful for others to post in the FAQs or knowledge base, is there one available that I may add the resolution to?

Thanks!

Dear all,
I have to upload for each file I check and validate (max 10KB each).
This happens with a frequency of 2-3 times per minute.
Unfortunately, the disconnection problem recurs often, even every 10 minutes.
I enclose what the debug window reports.
Thanks and good job.

Set up a very long SFTP transfer on a ethernet cable that's 400mbit limited. Suspect that it's a buffer overflow. Bug seems triggered when high-rate transfers happen ~37MByte/s

I'm not sure exactly how it happened, but it was after an SFTP host stopped responding in the background, and trying to close various dialog boxes.
No logs, sorry.

@alma.gideoni: Thanks for your report.

Hello - I was in the processing of downloading files that our former payroll service (ADP) had extracted to WinSCP for us. There were 23 zip files and I started the process of downloading all 'in the background'. When I went to check on the download process, I found that only 18 of the 23 zip files loaded. It looks like the download stopped due to ‘inactivity’??

I re-logged in to WinSCP – however – when I opened the ADP folder, there was only one zip file showing. I tried to download it and at first it looked like all was going well but it did not go through. When I tried to select download again, here is the message box I see. Not sure what happened to the rest of the zip files. Can you tell?

Screenshots attached. Thx for your help!

@monica.haut: Are you able to reproduce the problem? The files were probably meanwhile deleted from the server. Or doesn't the server automatically delete the downloaded files?
