Popen() and System() are things that security people look at. Has your
user turned on SELinux in non-Warn mode? Look at /etc/sysconfig/selinux
and see what is set up. Apache is one of the daemons that SELinux is
monitoring or controlling.
Grep for SELinux in /var/log/* to see if anything shows up there.
