Hello,
I understand some bugs were fixed around this issue of "Abnormal Disconnect" but i still get it when i do a "Ctrl + C" everytime!
Hi Paul, I'm sorry about the issue. What happens if you press "Ctrl + C" in Terminal.app after connect via ssh command line?
it ends the current running process, and i am still connected so i can do more commands.
I could not reproduced the issue, is it happens on all your hosts or just a specific one? And could you please enable debug log and paste the log here? Don't forget eliminate sensitive information from the log.

Hi Paul, thanks a lot for the debug log, will investigate this issue ASAP.
