core: Deconz stops responding, fixed after restart

The problem

Hey.

I’ve moved my Philips Hue setup over to my Home Assistant box a few months back (Raspberry Pi 3+, Conbee II). It’s been great until a recent update and now the lights randomly stop responding to button presses in Lovelace.

Restarting deCONZ fixes the issue. Latest versions of everything installed.

Logs below.

Anyone experienced this, know how to fix it?

Thanks. 😃
