Rabbitmq-服务器状态间歇性故障

来自 ubuntu precise 的 Rabbitmq-server 包：2.7.1-0ubuntu4

sudo service rabbitmq-server status并且sudo rabbitmqctl status在跑步和不跑步之间摇摆不定：

ubuntu@juju-cstack-machine-2:~$ sudo service rabbitmq-server status

ubuntu@juju-cstack-machine-2:~$ sudo service rabbitmq-server status

我已禁用与其连接的所有服务（仅一个）。我不知道该怎么做才能进一步排除故障？有什么想法吗？日志文件显然无益。

这似乎是网络和主机路由的某种问题。验证主机名并且可以通过 hosts 文件解析后，问题得到了解决。
