晚上好。面临的问题：在某些时候消息代理“浮动”（停止更新 Web 界面并建立连接）。当你尝试重启rabbitmq-server start命令进程停止响应后消息输出：

RabbitMQ 3.6.6. Copyright (C) 2007-2016 Pivotal Software, Inc.

Logs: /var/log/rabbitmq/rabbit@dbserver.log
/var/log/rabbitmq/rabbit@dbserver-sasl.log
Starting broker...

提示，如固定a？

附：命令systemctl status rabbitmq-server.service打印：

【解决方案1】：

虽然我无法验证退出代码 status=73 是否正是这个意思，但对我来说，这个问题原来是磁盘空间不足。如果您检查 rabbitmq 日志 (/var/log/rabbitmq/)，如果这是一个不同的错误，它应该会为您提供更多上下文。
