<I left my laptop with winscp open and connected by sftp to my vps (and I was connected to vpn network) then I came back to laptop and got winscp window active and tried to refresh my server's directory with ctrl+r and saw that nothing was happening, looked like it was disconnected from vps but there were no evidence that it was. The refresh sign was greyed out and I had no idea what was going on. I tried to go one directory up by clicking the '..' item in the files list and this resulted in the error window that took me here to write it for you! Hope this helps winscp to thrive.>

The problem happens rarely. I cannot reproduce it.

Did a search that spanned a large number of directories with a very large number of files. I got an error message from that which I don't remember exactly, but it was something like, Connection interrupted - if the problem persists, consider eliminating (something about a buffer size).

Then I aborted the search, but later found out that it seemed to keep running on it's own, even after the dialogue box had closed.

Then, I just clicked on one folder, which was not particularly large, and got the error message.

This is the first time that I have encountered this error, and it was immediately after upgrading to the latest version WinSCP. I have not encountered this error in the previous versions.

I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.
