On closing WinSCP it seems to keep a session alive. For instance if I reopen the windows session I find several notifications that the connection is broken. Today in addition I found this Memory Error. I could not close WinSCP. I had to go to Task Manager to individually kill several WinSCP tasks.

I'm looking (again) at WinSCP options to try to find a Close option that applies.

If you could provide a ticket number then I'll send evidence at least of the "keep alive but connection broken" messages when it appears.

It is not a big nuisance but it may be worth your while to know of it. Usual disclaimer: any advice gratefully received.

Thanks

I do not know what happened. I think that WinSCP was open and logged into a site when I put my Win 11 laptop in Sleep. A few minutes after I turned the laptop on I saw the WinSCP error.

I'm not sure when this happened. I have changed my internet connection between cellular and WiFi couple of times today and at that time my Cisco VPN connection is interupted for a short time too.

No clue what has happened since this winscp session has been behind other windows for a while.
