[GitHub] [dubbo] Lingzhou314 opened a new issue, #12625: The client has been closed and will not reconnect
Lingzhou314 opened a new issue, #12625:
URL: https://github.com/apache/dubbo/issues/12625
* Dubbo version: 3.2.2
* Operating System version: xxx
* nacos server: 2.0.3
* nacos client: 2.2.2
* Java version: 1.8
为什么收到服务变更通知，然后连上了，但是随后又立即关闭了，而且也不再重连了，导致这个消费者永远调不到这个提供者了
这个是启动日志

启动时候观察下网络连接状态看下是客户端断开的还是服务端断开的

这个是偶发的，不是必现，具体操作是我用Jenkins同时发布了十几个服务，包括所有消费者和提供者，而且他们都是单实例，但只有这一个消费者有这种错误，其他的消费者都是正常连接的，而且我重启这个消费者也能正常连接。只是不清楚为什么连接上了，又断开了是什么意思，难道是网络抖动的缘故，我们的服务都是部署在k8s里的，是同一个子网

@Lingzhou314 贴出日志是一个进程里打出来的吗？从日志中看起来似乎是自己连自己，并且有两个IP？

@icodening 是同一个进程里打出来的，102是消费者的ip，98是服务者的ip，这两条日志都是从消费者102这边打印出来的
