Many thanks to @wborn i’ll try your suggestion this weekend and report if it soves my problem.

Good morning, I re-installed Ubuntu 18.04 on my XU4 last night, and then OH2.3 with knx V1.12.0 All stable so far. I will report back in a couple of days Stefan

Great! It could be that the old binding uses more resources so the Java process never goes to the little cores. :wink:

When there are native issues with the KNX2 binding on your ODROID XU4 you will probably always see KNX packages in the stack of the hs_err_pid file. See my previous comment . Can you post the stack from one of the crashes of the hs_err_pid files? There’s also a thread about openHAB crashing on the …

That’s very good news @boxerfahrer ! :smiley: [image] boxerfahrer: I am disappointed though about the poor HW, but that’s a different story. There should at least have been a software fix for the default Java VM that’s part of the ODROID Ubuntu distribution. E.g. this CPU pinning approach or …

Hi I tried to follow these instructions, but got a warning about not having “Service lacks both ExecStart= and ExecStop= setting. Refusing.” Can you shed any light on this? (I’m not a programmer or coder, so I’m really out of my comfort zone) Any assistance would be welcomed. Cheers, Stuart c…

@wborn Running stable so far. Looks good. Pinning the java engine helped.
I wait another couple of days, then I plan to go back to knx V2
Thanks!
