我有一个在JBoss 4.2.2.GA上运行的企业应用程序，我遇到负载下的JVM崩溃。当我们转移到java 1.6.0_25时，我们看到了这种行为，同样的应用程序在JDK 1.5中运行良好
我们在观察者java.lang.OutOfMemoryError: PermGen空间加载时，以下是JVM崩溃报告。
崩溃报告在这里，我删除了一些引用我的应用程序的行

PermGen空间是JVM存储用户定义对象的类定义的地方。在JDK 1.5和1.6之间permgen分配可能不同，并且几乎可以肯定两个JDK生成的字节码不同，因此迁移后遇到问题并不奇怪。
使用以下开关在启动时为JVM分配额外的permgen空间：
-XX:MaxPermSize=XXXm其中XXXm是以兆字节为单位的数字。小心使这个数量太大，否则你可能会遇到其他与内存相关的问题。
您可能还想使用jvisualvm来分析您的应用程序服务器启动。也许你可以关闭一些不必要的功能。

（只是一个想法） - XML处理随着时间的推移而发生了变化。流行使用字符串内化String.intern（），将XML标记投入永久内存。这并不像看起来那么无辜。今天，通常使用唯一的映射。也许你有旧的显式设置。 http://www.ibm.com/developerworks/xml/library/x-perfap1/index.html
