<p class='note warning'>
There is an issue with the HBMQTT broker that can cause a memory leak (slowly increasing used memory). This causes an unstable system after the memory is full. You could measure/monitor this with a system monitor. The issue is from 2016 and could already be resolved with newer versions. Use another broker when you experience this issue, for example, Mosquitto. <br>

Link formatting was not working at the time, see you already fixed it and made it smaller. 👍

### {% linkable_title Owntracks%}

To use Owntracks with the internal broker a small configuration change must be made in order for the app to use MQTT protocol 3.1.1 (Protocol Level 4).
