Corda 节点 AMQ119007：无法连接到服务器。尝试过所有可用的服务器

Question

对于我的开发环境，我正在运行一个 https://gitlab.com/cordite/network-map-service，我在其中注册了我的 corda 节点。问题是它无法启动并出现以下错误。

 org.apache.activemq.artemis.api.core.ActiveMQNotConnectedException: AMQ119007: Cannot connect to server(s). Tried with all available servers.

我不太确定它指的是哪些服务器，因为显然网络地图中还没有其他服务器。看起来它可能与 artemis amq 内部有关，但我不确定。 关于如何解决这个问题有什么想法吗？ -_-

Answer 1

这可能是由僵尸 Java 进程引起的。尝试使用此处列出的命令杀死它们（https://stackoverflow.com/a/49425918/4620025）并再次运行网络地图服务器。
