Thanks all for looking into this. I dropped the .dll into my c:\cygwin64\bin directory and wasn't able to reproduce over 5 reboots. The minute I put back the original .dll, it failed again.
Let me know if there's anything else I can do to help.
Best to you all,
Brad

I didn't mention it originally because I didn't expect that would have an impact, but then I successfully tried 4 times with the ssh-agent/sleep 3. That's when I sent the email with what seemed to be a good workaround.
But after trying it the 5th time following your email, 1 of the 10 didn't pass. 🙁
I took out the ssh, and am seeing it there too, so that was not the issue. Drat.
So the delay helped, but didn't completely solve the problem. I have been stalling before starting the cygwin termincal/script for some minutes after a reboot, but that doesn't seem to make a difference either.
I can send you the script if you want to play with it.
Brad
