Apply ulimit globally on Ubuntu

Question

I need to apply "ulimit -s 256" to any system thread. Is there any way to achieve this under Ubuntu Server?

You can set user limits via pam_limits in /etc/security/limits.conf. See man limits.conf for informations about this file.

On Ubuntu 12.04 /etc/security/limits.conf does not appear to be read unless the following is added to /etc/pam.d/common-session.

session required pam_limits.so

Even then, it's not clear to me if it is picked up for programs started by upstart scripts.

Note that there is also a commented line in /etc/pam.d/su: # session required pam_limits.so. – CyberShadow Jan 17 at 8:00
