我相信一个程序员不应该犯这样的低级错误,后来看到原生代码,我做出一个比较合理的猜测,其本意可能是想通过调用Executor executor来异步执行,谁知小手一抖,在红色框那里输入了taskExecutor,而不是executor:problem code解决问题OK,知道问题的根因,想解决问题就比较简单了,将taskExecutor改成executor即可:private static Th...
12)ScavengeBeforeFullGC,设置为false,不允许在执行Full GC或者CMS的再标记阶段前执行Minor GC。 13)BindGCTaskThreadsToCPUs(仅JDK 8和JDK 11中),强制开启线程和CPU的绑定,参数设置为true,只在Solaris平台上有用。 该参数用于在CMS中对BOT结构中未分配空间的起始地址进行设置。如果设置该参数,在计算使用内存时会...
环境:服务器为centos,2个8核16线CPU,内存64G,jdk版本1.7.0_67 问题描述:服务器部署的java应用,jvm堆内存为8G,启动一段时间后CPU占用飙升到2300% jstack查看获得如下信息: "VM Thread"prio=10tid=0x00007f5ac4095800nid=0xa599 runnable"GC task thread#0 (ParallelGC)"prio=10tid=0x00007f5ac4021000nid=...
"GC task thread#7 (ParallelGC)" os_prio=0 tid=0x00007f0aa402a800 nid=0x68cc runnable 可以发现一致是full gc的线程在执行,占用cpu较高的资源,并且一致持续,表明一直达到了full gc的条件但是又不能回收掉内存从而占用大量cpu,导致程序不可用。
