Apache MQ Artemis - MQTT 保留消息对于连接到集群中其他节点的客户端不可用

I have 4 ActiveMQ 阿耳忒弥斯 2.10.1实例运行在cluster。客户端 (A) 连接到其中一个节点并发布MQTTQoS=0 的消息并且保留=真。当新的 MQTT 客户端 (B) 连接到另一个节点在集群中并订阅了该主题，之前发送的消息是没收到。当客户端 A 发布下一条消息时，客户端 B 会收到该消息。

这是 Artemis 中的一个错误，当客户端 B 连接到集群中的另一个节点时，客户端 B 没有收到 A 发送的保留消息，或者我丢失了某些内容？

如果我将客户端 A 和客户端 B 连接到集群中的同一节点，则客户端 B 在连接并订阅主题后会收到消息。

Broker.xml - 我使用poc.#用于测试：

你需要设置这个<address-setting>对于您关心的地址：

<redistribution-delay>0</redistribution-delay>
