PHP Curl doesn't load: GLIBC 2.16 not found

Question

Apache is throwing this error:
[Mon Sep 17 23:38:54 2012] [notice] Apache/2.2.22 (Unix) mod_ssl/2.2.22 OpenSSL/1.0.1b DAV/2 PHP/5.4.7 mod_perl/2.0.7 Perl/v5.16.1 configured -- resuming normal operations

Glibc 2.16 is, however, installed:
# pacman -Q glibc
glibc 2.16.0-4
# pacman -Q php
php 5.4.7-1
# pacman -Q curl
curl 7.27.0-1
I just noticed this problem, however it looks like this has been an issue for a while now (possibly since the glibc update?). My entire system is up-to-date, curl itself works fine from the command line. It just appears that there is an issue with this module. Any ideas? Thanks!

I have restarted Apache, but I have not restarted the whole machine (it's a server that's located 4 hours away from me with an intermittent remote superviser card), so it doesn't get rebooted often.
Would a reboot actually solve this issue?
