PermGen space的全称是Permanent Generation space，是指内存的永久保存区域OutOfMemoryError: PermGen space。从文字上看就是内存溢出，解决方法是加大内存。为什么会内存溢出，这是由于这块内存主要是被JVM存放Class和Meta信息的，Class在被Load的时候被放入PermGen space区域，它和存放Instance的Heap区域不同,GC(Garbage Collection)不会在主程序运行期对PermGen space进行清理，所以如果你的APP会LOAD很多CLASS的话，就很可能出现PermGen space错误。这种错误常见在web服务器对JSP进行pre compile的时候。如果你的WEB APP下都用了大量的第三方jar, 其大小超过了jvm默认的大小(4M)那么就会产生此错误信息了。
