Hi @alexkarageorgis ,
we have exactly the same Kernel and release running. So im not alone with my problems.
We figured out that it seems that there i a lot of load which could make the Problems.
So what i figured out in the meantime is that : https://community.openhab.org/t/openhab-4-0-1-and-network-pingdevice-on-docker-install-results-in-massive-threads/148658
So im pinging my network-devices to get the info if they are online or not. Openhab is making each ping-profile in a result of about 20 threads of arping per profile because it wants to ping the device from each existing bridge network which exists on the host. But i have this time no solution to only ping it from main network. You can see that if you open an interactive shell into container and make an “ps aux” and repeat this sometimes.
Maybe other impacts existing too but i did not figured out more.
So please let me know what you get out.
