是否可以获得正在运行的进程及其符号表的核心转储? [英] Is it possible to get a core dump of a running process and its symbol table?

问题描述

是否可以获取 gdb 或使用其他一些工具来创建正在运行的进程的核心转储及其符号表?如果有一种方法可以在不终止进程的情况下做到这一点，那就太好了.

Is it possible to get gdb or use some other tools to create a core dump of a running process and it's symbol table? It would be great if there's a way to do this without terminating the process.

如果可以，您会使用什么命令?(我正在尝试在 Linux 机器上执行此操作)

If this is possible, what commands would you use? (I'm trying to do this on a Linux box)

推荐答案

$ gdb --pid=26426
(gdb) gcore
Saved corefile core.26426
(gdb) detach
