java.util.concurrent.TimeoutException:创建akka actorSystem时，Futures在[3000毫秒]后超时

我正在使用akka集群输入输出项目

以下是akka配置-

    akka {
      loggers = ["akka.event.slf4j.Slf4jLogger"]
      loglevel = "DEBUG"
      logging-filter = "akka.event.slf4j.Slf4jLoggingFilter"

      actor {
        provider = "akka.cluster.ClusterActorRefProvider"
        creation-timeout = 20s
        warn-about-java-serializer-usage = on
        enable-additional-serialization-bindings = on
      }

      remote {
        log-remote-lifecycle-events = off
        log-frame-size-exceeding = 15 MiB
        artery {
          enabled = on
          canonical {
            port = 2551
          }
          advanced {
            maximum-frame-size = 15 MiB
            buffer-pool-size = 1024
            maximum-large-frame-size = 15 MiB
            large-buffer-pool-size = 4096
            outbound-message-queue-size = 4096
            outbound-control-queue-size = 20000
            outbound-large-message-queue-size = 4096
          }
        }
      }

      cluster {
        seed-node-timeout = 15s
        retry-unsuccessful-join-after = 15s
        shutdown-after-unsuccessful-join-seed-nodes = off
        auto-down-unreachable-after = off
        seed-nodes = ["akka://ClusterSystem@SERVER1:2551", "akka://ClusterSystem@SERVER2:2551"]
      }
    }

Actor系统是使用-

package com.mycompany.akka;

import com.typesafe.config.Config;
import com.typesafe.config.ConfigFactory;
import akka.actor.ActorSystem;

public class ActorSystemFactory {
    public static ActorSystem getActorSystem() {

        try {

            String hostName = String hostName = InetAddress.getLocalHost().getHostName();

            Config cfg = ConfigFactory.parseString(
                    "akka.remote.artery.canonical.hostname=" + hostName).withFallback(
                    ConfigFactory.load());

            String prop = System.getProperty("cluster_name");
            if (prop == null)
                throw new Exception("property cluster_name is not set");

            ActorSystem as = ActorSystem.create(prop, cfg);
            return as;
        } catch ( Exception e) {
            e.printStackTrace();
            throw new RuntimeException(e);
        }
    }
}

我始终能够看到actor系统因以下错误而关闭-

actor系统存在什么问题？如何解决此问题？

工作解决方案：

我也不得不努力找出确切的解决方案，这里是基于我能找到的例外情况。您必须在akka->actor->remote->artery->bind配置中添加bind.bind-timeout

  remote.artery {
    # The port clients should connect to.
    canonical.port = 2551
    bind.bind-timeout = 30s
  }
