Question

根据文档，我们可以设置一个空DB的集群但是，按照设置具有现有数据库的集群的说明，我们遇到故障，10分钟后，所有三个核都会抛出异常。
这可能是由于： causal_clustering.join_catch_up_timeout = 10m
但是数据库已经同步，因此启动应该是即时的＆＃34;

任何指出我们正确方向的信息都将受到赞赏。

请检查以下配置是否适合您的集群。 1）neo4j.conf 正确配置了每个因果群集的“ dbms.connectors.default_advertised_address”，并且这些IP地址可以相互访问。另外，将“ dbms.connectors.default_listen_address”设置为0.0.0.0 2）取消绑定节点并重新启动它们。

让我知道您是否仍然看到该问题。
