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

Hi Martin it's conrad, I was navigating to a folder by double clicking in folder sync, and the server seemed to me to lag, I had a putty session open too that also got booted, however in winscp the "reconnect 30s countdown" eventually appeared *after* an inordinate amount of wait (~30 s)> then it went mad with this EEEFAACE error
