Before posting, please read how to report bug or request support effectively.
Bug reports without an attached log file are usually useless.
Finally I seem to have found something useful: NetworkTrafficView. But have not found a problem yet, there are only two connections from WinSCP, and one from phpStorm. I will keep watching and report here if I find anything interesting.
Anyway, could you please clarify: Is the "Maximal number of transfers at the same time" the same as max. connections? Or can there be several connections per transfer?
Shutting down WinSCP does not help.
