服务端版本:2.3.2/2.4.2.1 客户端版本:2.3.2 三个节点组成的一个集群,不定时的会出现个别节点CPU飙升,使用率达到100%,进程挂掉的情况。
线程运行情况:
使用netstat命令,查看到9848,9849端口有很多CLOSE_WAIT状态的连接。

没有遇到过这个情况, 操作系统是windows吗?
Sorry, something went wrong.
操作系统用的麒麟 NAME="Kylin Linux Advanced Server" VERSION="V10 (Sword)" ID="kylin" VERSION_ID="V10" PRETTY_NAME="Kylin Linux Advanced Server V10 (Sword)"
可以打印一下CPU占用高的线程的堆栈, 看一下是否是Nio的Selector占用了CPU资源, 如果是的话,那应该是jdk NIO的bug,和window上的问题一样,
如果不是的话, 可以把堆栈贴出来, 看一下什么地方占用了过高的CPU。
也可以用arthas抓一下火焰图,可能更直观一点。
