You have pause_minority mode enabled. From<br>

In pause-minority mode RabbitMQ will automatically pause cluster<br>

<br>
So when you stop two nodes, the third determines itself to be in a minority=
, and pauses, becoming unresponsive.<br>
<br>
If this behaviour is not what you want, then you don&#39;t want pause_minor=
ity mode.<br>
