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.

Didn't do anything really. Kept Winscp running overnight with connected sessions. Overnight, some connections dropped. When I started to use the computer again in the morning - 10 minutes after I did so - Winscp started to give many of these errors in quick succession.
