Do I need to reboot the machine after increasing the maximum number of open files at /etc/security/limits.conf?

No, you don’t need to. This morning I struggled to convince someone that the server does not need a reboot. It was because of this: Increasing the number of file handles on Linux workstations.

ulimit – Provides control over the resources available to the shell and to processes started by it, on systems that allow such control.

limits.conf is configuration file for the pam_limits module

It takes effects immediately upon re-login. It’s hard to explain things that only you understand internally. I wish I have a formal Red Hat training so that I can explain better.

In the end I just rebooted the system so that other person who thinks (he/she) knows everything will be satisfied. Now (he/she) is.

Those struggling to get some proof you can probably forward this url which should have better reputation than this blog.
