ignite服务器出现一些与线程相关的异常

Question

其中一个ignite服务器提供了一些线程相关的exception.Below是一些stackTrace：

谁能告诉我为什么这些线程相关的异常会出现。当另一个具有相同服务器实例名称的服务器启动时，我收到此错误。我知道服务器正在被关闭，因为上面的reason.But，为什么这些线程相关的错误来了。我还在最后发布了ignite服务器的java代码。

以下是Ignite服务器代码。

public IgniteConfiguration createConfiguration() throws Exception {
    IgniteConfiguration cfg = new IgniteConfiguration();

    cfg.setIgniteInstanceName("CcPlatformUserRolesOrganizationAssociationServerGroups");
    cfg.setSqlSchemas("public");
    TcpDiscoverySpi discovery = new TcpDiscoverySpi();

    TcpDiscoveryMulticastIpFinder ipFinder = new TcpDiscoveryMulticastIpFinder();

    ipFinder.setAddresses(Arrays.asList("127.0.0.1:47500..47510"));

    discovery.setIpFinder(ipFinder);

    cfg.setDiscoverySpi(discovery);
    cfg.setPeerClassLoadingEnabled(true);
    // setting Cache
    cfg.setCacheConfiguration(cacheGroupsCache());

    return cfg;
}

这些不是异常或错误。它是一个线程转储，显示JVM中每个线程在特定时刻的活动和状态。Ignite配置为在检测到故障时自动记录线程转储。您可以使用IGNITE_DUMP_THREADS_ON_FAILURE系统属性来更改这一点。更多信息请点击此处：https://apacheignite.readme.io/docs/logging
