Possibly related? [image] JavaScript memory/stability issues Scripts & Rules Hi, I’m taking the first baby steps towards migrating my DSL rules to JavaScript. Unfortunately I’m starting to see a pattern: Every time I edit and trigger a rule a few times, my sy…

thanks for pointing this out. I link my post to that topic and once it is clear it is the same problem, I’ll delete me post

My message was split from the official 3.2 release thread. And when talking about new JS scripting it is clear, that it HAS to be OH3.2 version. But yes I could provide details that I have the latest openhabian version and run Zulu11-32 (latest version) - I always do an update before posting issues…

[image] Oliver2: In contrary to your problem, my OH is stable, no increase of CPU performance. Only if I modify and test JSscripting scripts which causes errors due to wrong syntax after a short while my CPU load goes up to 100% and stays there until a restart. This is what is happening to m…
