HPUX GDB 分析core文件

1、file core；

       进入core文件所在目录执行如上的命令；

      返回如下内容：

Core was generated by `Edr2'.

自重Edr2服务就是产生core的tuxedo serverices服务名；

2、gdb '服务名' core

       执行以上命令格式返回如下：

$ gdb Query core

(gdb)

 

3、where

(gdb)where 执行返回：

     现在基本你能看到产生core文件是由于上面代码行调用期间引起的，你可以针对以上提示的代码行进行处理，一般来说产生core原因由于内存泄露或者变量使用不当造成；
