Java 使用hazelcast时地图未准备就绪

我使用的是hazelcast v3.2.4客户端和服务器。服务器从数据库加载数据-此问题不会发生在数据较少的情况下，因此我猜测其数据大小与此相关，但需要确认。我在服务器中有两个节点用于测试——一旦知道问题所在，我可以添加更多节点。下面提供了我用于hazelcast地图的地图配置。我不确定我是否以某种方式对地图进行了错误配置。客户端和服务器上的错误如下所示。我不确定是它的GC还是节点上太多的数据simple top check显示内存使用率低于35%——我将很快使用jvisualvm进行检查

客户端错误

服务器

确保您执行了以下所有操作来调试并修复

在运行hazelcast服务器的服务器上运行jstatd，例如。 jstatd-J-Djava.security.policy=jstatd.all.policy-J-Djava.rmi.server.hostname=xxx.xxx.xxx.xxx 然后连接jvisualvm以了解服务器应用程序的情况。您还可以使用top获取流程的基本信息

分享您如何启动java进程—服务器上有多少可用内存。您指定的java进程的Xms和Xmx值是什么

如果仅仅改变步骤2并不能解决您的问题，请尝试使用G1GC

如果步骤2和步骤3不起作用，请尝试向服务器群集添加更多服务器

这是在运行服务器之后还是在运行一段时间之后发生的？内存使用情况是否会根据应用程序的工作方式而变化

我增加了Xms和Xmx，并切换到G1GC，这个问题似乎已经消失了。顶部显示了几乎90%的内存使用率。因此，要么我需要减少内存中的数据，要么添加更多节点。
