[D] broker master宕机卡死之后，client端还继续往broker 发送消息 [rocketmq]

GitHub user BruceMiao305 created a discussion: broker master宕机卡死之后，client端还继续往broker 发送消息

集群版本4.1.0 ，客户端版本3.2.6
现象：
其中一台物理机器卡死，nameserver包括客户端日志能看到remove卡死机器的broker master。
时间：8:56:20broker master卡死，客户端和nameserver都感知到了。

日志：
2024-05-28 09:08:54 INFO NettyClientWorkerThread_4 - closeChannel: the channel[172.16.168.14:16911] was removed from channel table
2024-05-28 09:08:54 INFO NettyClientWorkerThread_4 - NETTY CLIENT PIPELINE: CLOSE 
2024-05-28 09:08:54 INFO NettyClientWorkerThread_4 - eventCloseChannel: the channel[null] has been removed from the channel table before
但是客户端还是一直会与挂掉的节点建立连接，重复的remove，所以很奇怪，麻烦大佬们帮忙看看，解答解答，或者又遇到类似现象的一起讨论一下。

这个集群版本以及客户端版本都太老了，现在都5.2.0了。可能在客户端处理路由方面存在问题，建议升级到较新点的版本吧，例如4.9.x。
