为什么Coredump文件未在此处生成? [英] Why Coredump files is not generating here?

问题描述

我在这里有个情况，几天前我能够在目标板上看到核心哑文件，我通过在/etc/profile中添加"ulimit -c unlimited"来提供了核心转储生成支持.告诉我

I have a sitution here,few days back I was able to see core dumbed file on my target board,I have provided the coredump generation support by adding "ulimit -c unlimited" to my /etc/profile.But then someone told me

这仅对从登录shell启动的程序有效，而对systemd启动的进程/服务无效，etc/limits将是设置这些默认值的正确位置.

This will only take affect for program launched from a login shell, not for processes/services started by systemd,etc/limits would the the proper location for settings these defaults.

所以我更改了/etc/limits文件并添加了"ulimit -c unlimited"行.但是现在我看不到已简化的文件

So I changed /etc/limits file and added "ulimit -c unlimited" line.but now I could not see Coredumped file

我正在运行kill -9 $$来生成分段错误，它反过来会像以前一样生成coredump文件.

I am running kill -9 $$ to generate segmentation fault and it in turn will generate coredump file as it was doing earlier.

我们尝试更改"/proc/sys/kernel/core_pattern"文件并显式运行ulimit -c unlimited，但它也无法解决

We tried changing "/proc/sys/kernel/core_pattern" file and running ulimit -c unlimited explicitly also but its not working out too

我们在哪里做错了?

推荐答案

kill -9不会生成 core 文件.命令kill -l列出了支持的信号. kill -6或kill -SIGABRT应该产生一个核心文件.以及大多数其他信号，例如kill -BUS，kill -SEGV等

kill -9 will not generate a core file. The command kill -l gives a list of supported signals. kill -6 or kill -SIGABRT should produce a core file. As well as most other signals such as kill -BUS, kill -SEGV, etc.
