Creating core dump

typecast · 2007-03-08 14:30:45

Hi,

i want to debug some programs and i therefor want them to core dump on segmentation fault. But i'm not able to make arch create a core dump file.

The problem is that i'm not allowed to change ulimits. Whenever i try to change it with my normal user account i get:

lothar@timbutu:~$ ulimit -c 10000
bash: ulimit: core file size: cannot modify limit: Operation not permitted

Root does not have this problems. I tried to set reasonable limits in /etc/security/limits.conf:

* soft core 100000
* hard core 100000

but that didn't help. Any ideas?

Regards,
Lothar

Hym, setting limit as a user works here.

What groups does your normal user belong to? I'm in

10(wheel),91(video),92(audio),93(optical)

Do i need to join another group in order to change the limits?

Are you in "users" group?

No, i wasn't. But joining users and relogin didn't help. I still get

lothar@timbutu:~$ ulimit -c 10000
bash: ulimit: core file size: cannot modify limit: Operation not permitted

I have no idea. Works properly on both of my boxes.

Maybe try reinstalling pam (pacman -S pam).

I tried to reinstall it, but that didn't help.
