PermGen space


PermGen space的全称是Permanent Generation space,是指内存的永久保存区域OutOfMemoryError: PermGen space从表面上看就是内存益出,解决方法也1定是加大内存。说说为何会内存益出:这1部份用于寄存Class和Meta的信息,Class在被 Load的时候被放入PermGen space区域,它和和寄存Instance的Heap区域不同,GC(Garbage Collection)不会在主程序运行期对PermGen space进行清算,所以如果你的APP会LOAD很多CLASS的话,就极可能出现PermGen space毛病。这类毛病常见在web服务器对JSP进行pre compile的时候。

解决方法


只需要在Tomcat的bin目录下的“”文件中添加1行就能够解决问题

JAVA_OPTS='-Xms512m -Xmx2048m -XX:PermSize=128M -XX:MaxNewSize=256m -XX:MaxPermSize=256m'
