Error while starting Jboss server: Exception in thread "pool-6-thread-5" java.lang.OutOfMemoryError: PermGen space

JBoss AS 6.x 每当我尝试启动它时都会因以下错误而崩溃。

错误：

启动时添加此 VM 参数 JBoss :

-XX:+HeapDumpOnOutOfMemoryError

这将在 JBoss 遇到 OutOfMemoryError 时生成一个 hprof 文件。

可以使用 Eclipse MAT 等工具分析此文件，并告诉您哪些对象使用更多内存。
