[SOLVED] Why Coredump files is not generating here?

Issue

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

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.

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

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

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

Where we are doing wrong??

Solution

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.
