Thank you. Maybe I should have rephrased when I said “which based on search results is a known issue with executeCommandLine”. I’m referring to this thread (OH 1.x and OH 2.x Rules DSL only] Why have my Rules stopped running? Why Thread::sleep is a bad idea which is exactly the issue I am having.
I am running executeCommandLine with a timeout (since otherwise I am not getting any output back). And that in turn is causing (at least my cron timer based) rules to stop running after a couple of days.
Good shout. I will try the stopping / clearing cache / restarting tomorrow. There is nothing in openhab.log. Will check events.log.
