Warning in my logs every 10 seconds?

hi all, I’m running openhab 2.4 on a rpi 3

I’ve got a weird error in the logs that’s happening every 10 seconds and im clueless as to what’s causing it.

any ideas as how to stop it would be awesome.

cheers

This is a warning rather than an error, meaning it likely will not affect any functions, but I understand that this annoying.
It looks like the yamaha binding may be causing this. You can verify this by uninstalling all other bindings…
but maybe the easiest first try is to restart OH2 and if that does not change anything, you may want to Clear the Cache
