Hi Andrew,
I'm not using W10 components, I have only cygwin installed with open-ssh and rsync.Unfortunatelly disable_pcon didn't help, I have the same issue :
- ssh-keygen hangs- sshd - hangs with high CPU usage ( 100% split on number of instances )- I don't see any handles or files open by sshd or ssh-keygen- when debuggin with windbg I got cygwin1.dll waiting for a get_perm_acl, but only once
BTW, I'm runnig sshd as service, but also in console, via bash, is hanging.
Could it be that the fact that W10 is in a VMWare has some impact on cygWin ?
Regards,
Cezar Damian

This can be an external (to Cygwin) issue, and I see tha tyou are indeed using
Cygwin's ssh-keyegen for all that I can tell, but please double-check that you
aren't actually using Win10 peovided OpenSSH components.
To the hangs, try running them with CYGWIN=disable_pcon for a test.
