Reporting the same issue. This has been an ongoing problem for me. I first upgraded to OH4 when M1 first got released in early March 2023. I enjoy helping and figured I’d test the new version. I immediately began to have problems with the cpu going over 100% causing the host to get very sluggish. The Host is a small Dell brand desktop running Mint Linux with I3, 8Gbs Ram and 1Tb spinning HD so not a rocket, but not a Pi. It does very little other then run openHAB.
I reported the issue in the snapshot discussion thread here and also found another thread that seemed similar to the problems I was having. I figured it was unique to my setup because no one else seemed to be reporting similar problems.
Eventually I thought I had found the culprit as being a rule which had a syntax error. I disabled the rule in question and the problem subsided but didn’t go completely away. I have since occassionely still had the same. I continue disabling other rules, my system has been crippled for months. I’m not surprised to see this thread because I always felt there was a more underlying issue then just my rules having a syntax error.
