我正在为活着测试做POC，看到了一个奇怪的场景，它开始为所有集群节点计时。我打算使用这个活性测试API在HAProxy中使用应用程序级别的运行状况检查。但是当HAProxy开始将所有群集节点显示为DOWN时，这种情况让我感到害怕，因为在所有群集节点的活动测试超时但是Rabbitmq服务器端口在此期间是可连接的。根据文档，可以假设rabbitmq管理工具（侦听端口15672）可连接，而服务器（侦听端口5672）已启动并运行。
当我重新启动兔节点时，它处于相同的状态。
当我使用kill -9在所有主机中杀死rabbitmq进程并正常启动应用程序时，它恢复并开始返回响应代码200。
如何避免这种情况？
