Cleaning up OH2 startup warning erros

I get a number of startup warnings I would like to debug.

[WARN ] [] - Execution failed (Exit value: -559038737. Caused by Cannot run program "arping" (in directory "."): error=2, No such file or directory)

I actually do not have any commandexec lines right now.
Any idea what is arping?

What about doing a forum search for arping?

Right, I search for most of the words except arping.

If you’re on debian based linux, you should be able to fix that with “apt install arping”

It is very weird but after installing arping, my Ikea gateway hung up every 30min or so.
Something to do with the apring’s way of auto-discovering or checking for services?

I removed the ikea gateway from the network binding and hid all things that have the gateway IP.
I had the pin interval set to 60seconds, and later to 10min - so I doubt that this was the issue.

I will try to look into this a bit further in the future.
