modify /etc/security/limits.conf without reboot?

[Zachary Stern]

Is there a way to modify /etc/security/limits.conf without a reboot?

E.g. if I add the following:

+root hard nofile 20000
+root soft nofile 20000
+www-data hard nofile 20000
+www-data soft nofile 20000

Can I just restart apache, which runs as www-data? I'd like to find a way
to avoid rebooting.

TIA.
