Out of swap space

Just posting my version of this, slightly modified and also hopefully forum formatted for ease of copying and pasting!

Quick one: if I’m using

mqtt:
  broker: core-mosquitto
  discovery: true
  discovery_prefix: homeassistant 

as my MQTT settings, does that mean I’m running the HBMQTT (embedded) or RabbitMQ broker? I’m confused, as there seem to be a lot of potential built in brokers. I THINK I’m using the Eclipse Mosquitto broker Hass addon. Just trying to rule out the source of the memory leak. I AM running the Unifi addon…
