[rabbitmq-discuss] RabbitMQ node stopped while broker still up

Wed Oct 17 10:58:37 BST 2012

Hi Simon,

Usually i used command "/sbin/service rabbitmq-server stop" to stop the
rabbitmq.

Is it possible the command invoke the "rabbitmqctl stop"?

If yes, then it explain the situation.

Regards,
Wong
