High CPU Utilization

Since updating to 0.72 ( and the same in 0.72.1) i’m seeing a massive increase in CPU utilization.
Utilization will be relatively low with the occasional spike until i access the UI, then it jumps to 100% and it appears that a second instance of /usr/bin/python3 -m homeassistant --config /config starts.

I’m running Hass.io within docker on a debian server.
