High CPU usage caused by Java crashes OpenHab3

Setup, Configuration and Use Runtime

Hello,
maybe someone already had such a problem and was able to solve it successfully.
After a fresh OpenHab start, the CPU utilization immediately jumps to extremely high values.
The process is associated with Java (image of processes attached) /snap/openhab/1670/bin/java -version

This ensures that OpenHab becomes unusable after a very short time, crashes, hangs, restarts, is unreachable, throws 404 errors and all sorts of things.

I’ve tried all OpenHab versions, whether with stable, milestone or snapshot, always the same process.

java -version outputs the following:

openjdk version "11.0.15" 2022-04-19 LTS
OpenJDK Runtime Environment Zulu11.56+19-CA (build 11.0.15+10-LTS)
OpenJDK Client VM Zulu11.56+19-CA (build 11.0.15+10-LTS, mixed mode)

This is on a brand new fresh install? Any bindings installed?

3

No, it’s not fresh and there are some bindings in use, worked without problems for months. I didn’t install any new binding since then that could cause this problem.

What does a

mean then, in this context? What steps are you performing?

6

For example when I reboot my Raspberry and OpenHab is set to autostart. Or if I stop the OpenHab service in Terminal and then restart it again.

Did you find a solution because my install does the same and the cpu is at 95 percent, at this time OpenHab becomes inaccessible, I stop, I empty the cache and I restart, but it comes back quite often

Yes, I’ve update to a newer Java version:

openjdk version “17.0.1” 2021-10-19 LTS
OpenJDK Runtime Environment (build 17.0.1+12-LTS)
OpenJDK Server VM (build 17.0.1+12-LTS, mixed mode)

And switched to openHAB 3.3.0-SNAPSHOT

Now it’s stable for weeks.
