Hi. Sorry so late at this, but replying to thank you for your suggestions, Strahil. I finally figured out (again, it has been a while, I just failed to reply) that (I think) I needed to (again?) increase maxproc-cur for the default login class (per id -c), in /etc/login.conf and log back in. I have had to do that again after upgrading to 6.9 and 7.0 also, for several values, but fortunatly the email from sysmerge prompted me in a way. And now I can open as many terminal windows as I want. I also don't ssh as much locally, now that I understand xauth better, thanks to info such as found in Part 8 of: https://www.exoticsilicon.com/jay/reckless_guide_to_openbsd/ ...and very helpful pointers from Crystal Kolipe. All the best, -- Luke Call * Are info sources trustworthy? How do we know? Based on identifying, and observing trustworthy behavior over time, of the original eyewitness, and all reporters in the chain to us? And corroboration by other such? * Happy to discuss, or: http://lukecall.net - Tech, many thots, peace amid commotion, fun. (Cmts/sugg welcome. https later.)
