    这是一个创建于 3638 天前的主题,其中的信息可能已经有所发展或是发生改变。
    一个j2ee web项目,跑在tomcat里面,没啥并发,放在那里自己空转,即使这样,Tomcat都会自己挂掉,然后整个jvm退出,这个该如何入手分析呢

    挂掉的时候,kill -3 pid试试,看下内存的分配情况
    以及,通过jmap方式,得到当时的heap情况,使用Eclipse Memory Analyzer tool来分析

    加参数,看有没有dump.core文件出现。

    还可以用jconsole来观察

    1. 观察内存情况
    jmap -heap pid

    2. dump 线程情况
    jstack pid

    3. 增加:
    -XX:+HeapDumpOnOutOfMemoryError

    4. 分析堆栈情况

    5. 再不行就 google 如何分析
