2,通过jstat命令看到,Jvm中Old区不断增加,FullGC非常频繁,对应的FullGC消耗的时间也不断增加 3,通过jconsole/jvisualvm可以看到,堆内存曲线不断上升,接近上限时,变成一条直线 4,日志报错java.lang.OutOfMemoryError: Java heap space 内存泄露怎么定位? 1.确定征兆:现象方面,Java进程抛出OOM异常,分析属于那种异常,...

一、java.lang.OutOfMemoryError: PermGen space PermGen space的全称是Permanent Generation space,是指内存的永久保存区域,这块内存主要是被JVM存放Class和Meta信息的,Class在被Loader时就会被放到PermGen space中,它和存放类实例(Instance)的Heap区域不同,GC(Garbage Collection)不会在主程序运行期对 PermGe...

按照JVM规范,除了程序计数器不会抛出OOM外,其他各个内存区域都可能会抛出OOM。 最常见的OOM情况有以下三种: java.lang.OutOfMemoryError: Java heap space --->java堆内存溢出,此种情况最常见,一般由于内存泄露或者堆的大小设置不当引起。对于内存泄露,需要通过内存监控软件查找程序中的泄露代码,而堆大小可以通过虚拟...
