Memory Leak / High CPU Usage of Z-Wave-JS Addon

Dear community,

My SD card crashed (as in, not readable at all) including all the backups of my Home-Assistant installation. Shame on me and lesson learned.

However, after a fresh clean install of Home Assistant OS on my Raspberry Pi 3b with a Z-Wave module installed on the GPIO pins I installed the Z-Wave JS Addon. Now my problem is, that it uses constantly around 40% CPU usage and the memory consumption keeps rising until the entire Raspberry Pi becomes unresponsive and I have to pull the power plug to do a reboot. If I stop the Addon before, it releases the memory and everything is back to normal.

Now my issue is, how do I debug this? I don’t see any error message in the addon’s logs. This is when I am launching on debug log level.

Any pointers help would be really apreciated.
