Mysql Mariadb Galera节点将不会成功重新加入，除非它选择一个特定节点通过

Debian 10，Maridadb 10.3.26，Galera-3 25.3.31

我有一个三节点集群。这些节点被命名为node3、node4和node5。Node3有时会与集群断开连接

如果它选择点头5从我得到的

在这之后，node3将永远坐着，永远不会改变你准备好了吗

另一方面，如果node3选择node4，我会收到所有相同类型的消息，除了

[警告]WSREP:协议冲突。加入消息发送方2.0（节点5）未处于状态传输（已同步）。消息被忽略。

不会出现，最终节点3 wsrep_ready变为yes，节点开始处理查询

你知道我对这个问题了解多少吗

这里还有一些数据。这是选择node4而不是node5时成功连接的示例：
