I did not report the first, and it was a known issue. The second one was mine. My workaround was to disable the daily network heal and restarting OH. I can still heal individual devices, if needed.
It’s a rare issue, possibly related to large networks (>120 devices). Chris is extremely busy, and with all the changes this year, the IDE is not what it was, especially when it comes to debugging.
I’m not the right person to ask, but the 2.5M2 preparation topic may shed some light on that.
