I am already familiar with everything you wrote (with regards to rules, and thanks to this thread, also with regards to timers).
I don’t use any Thread::sleep, all my sendHTTP* calls were within createTimer to prevent rules hanging, and apart of this my rules don’t use any timers (I do have 16 cron-based rules and 3 astro-based rules, but they are all well spread along the day).
I am not familiar, though, with the OS, how it should behave, and how to analyze the usage of resources, and making sure it works as it should, or I should look into specific areas and analyze them.
As @rlkoshak wrote,
I am looking for what causes the number of threads growing on my system, and whether this is a "temporary"grow (and threads get released over time) or it is a “constant” grow.
If it helps, my setup is using openhabian over a RPi 3B+ with the following bindings:
- Astro (only 3 very short rules are triggered by the astro binding)
- Expire (~30 items using it)
- HarmonyHub
- Xiaomi Mi (2 nodes connected to it)
- Network (pinging 4 iPhones)
- Samsung Tv (polling every 1 second)
- openHAB Weather (polling every 2 minutes)
- YamahaReceiver (polling every 10 seconds)
- ZWave (~22 nodes connected to it)
Also using:
- openHAB Cloud connector
- Google Calendar connector
- Mapdb for RestoreOnStartup
- Influxdb for some other items (installed grafana as well, but didn’t “play” with it too much, yet)
Here is a the full bundle list:
