A Little more info: I actually have 1 client that connects regularly to the server. That client uses a program called goodsync. When I block goodsync from connecting, the problem goes away and I only have 1 sshd.exe process running. When I unblock goodsync, I have multiple sshd.exe processes running and my cpu gets maxed out. Please test it like this. Thanks. On 5/20/2021 12:02 PM, A. Doggy wrote: > Anyone? > > On 5/19/2021 12:48 AM, A. Doggy wrote: >> To Cygwin, >> >> >> I am running cygwin openssh as a windows service.
