This is OH3.2 running on Linux in a vm (to allow for more RAM and CPU power than a raspi 3B can offer).
The install is filebased (.things, .items, etc) and the rules are jython jsr223. Sensors and actuators are connected via MQTT.
After OH starts everything works nicely and just like expected. After a number of days things may get wiered. The symptom is that some behaviours of my system stall:
Some lights in the bathroom won’t turn on, but not all are affected. The rules for pir1 and pir2 are ignored, I can see the mqtt message, it gets read and parsed and an item changes, I see the event with those commands and the change event in the event.log. But the rule doesnt seem to receive the event.
And at the same time the pir4 - which is very similar, turns on another light and has it’s rule in the same scriptfile - still works as it should.
When that happens a number of rules in different script files typically are affected. I couldn’t find a common property among them though. A lot of breadcrumping that usually goes into openhab.log stops - but again, not all of it.
When I now edit and save a script file I won’t get the "Loading script ‘filePath’ " line in the .log file. And I don’t see the changes I made being applied.
RAM usage looks normal (1GB) and java is in the single digits when I look at
Basically, I can do and try what I want, the only measure that sets things right again (including the changes I just made ) is to restart openHAB. Done in a couple of minutes but this is not satisfying.
I don’t know what is happening and, worse, I have no idea where to look for pointers. I guess I should enable debug for some parts but which? how? and can I direct those debug outputs into a dedicated file so they do not spill over the openhab.log?
Thanks in advance for any idea or pointer!
