JVM java内存溢出

阿里云文档 | Java应用启动加速的JVM参数配置
文章 | JVM系列之：你知道Java有多少种内存溢出吗
问答 | [@talishboy][¥20]1、jvm是可以设置内存上线大小的但是在现实情况下java的内存溢出有大致两类，堆内存区和PermGen区当我设置PermGen的上线大小例如1g感觉已经不少了，可是容器依旧OutOfMemoryError，所以有什么好的意见可以调优调试，或者精准的跟踪问题？2、session的问题，使用spring-security 当session失效的情况下（服务是正常的）用户在再次login之后重复跳回login导致请求被重新拦截了，请问如何排查？
