The parallel collector will throw an OutOfMemoryError if too much time is being spent in garbage collection: if more than 98% of the total time is spent in garbage collection or less than 2% of the heap is recovered by garbage collection, an OutOfMemoryError will be thrown. This feature of throwing GC overhead limit exceeded message is designed to prevent applications from running for an extended period of time while making little or no progress because the heap is too small. --原因是垃圾回收器因为某些原因花了非常长时间。并行的垃圾回收器抛出内存溢出的错误。要么是花了非常长时间做GC的操作或是仅仅有2%的堆内存又来回收。GC overhead limit exceeded被设计出来是为了阻止应用程序执行的时候。因为堆内存设置的小而没有进展。 SOLUTION You can avoid the above java.lang.OutOfMemoryError: GC overhead limit exceeded exception by disabling the GC overhead limit feature in Sun JDK 1.6 by adding the following argument to the start script of JVM: -XX:-UseGCOverheadLimit However, please note that disabling the overhead limit only avoids getting the OutOfMemoryError at an early stage. The OutOfMemoryError is very likely to be thrown at a later stage, because it does not remove the underlying problem. You should still look into your application and JVM settings to find the cause of GC taking an excessively long time. --避免这样的错误在JVM中显示设置-XX:-UseGCOverheadLimit 转载于:https://www.cnblogs.com/gcczhongduan/p/5261314.html
