出于测试目的，我正在集群中运行4个hazelcast实例。当我的服务器在hazelcast客户端上运行了12个小时时，出现此错误。我为客户提供的代码如下。
ClientConfig config = new ClientConfig();
config.getNetworkConfig().addAddress(ip);
config.getNetworkConfig().setConnectionAttemptLimit(0);
config.getConnectionStrategyConfig().setReconnectMode(ClientConnectionStrategyConfig.ReconnectMode.ON);
//SubZero.useAsGlobalSerializer(config);
GroupConfig groupConfig = config.getGroupConfig();
groupConfig.setName("dev");
config.setProperty("pool.size", "" + SystemInfo.getSystemCore());
config.setProperty("hazelcast.logging.type", "log4j");
setHzClient(HazelcastClient.newHazelcastClient(config));
仅供参考，错误的堆栈跟踪如下：
