Maybe there's an ntp expert out there who can help me with this. I
have an NTP server serving our local network. It is set up to use
pool.ntp.org servers for it's upstream sync. ntpq -p reveals that
the server is stuck on stratum 16, which I understand means "not
synced". The clients are unable to sync with my local server
because of this. Here's the output of ntpq -p along with my
ntp.conf file:

Name resolution is working correctly, but, yeah, there's no sync-ing
happening.

This is almost certainly incorrect unless you're running a very, very
old RHEL/CentOS release. I believe /var/lib/ntp is the canonical
directory for the drift file in 4.x and 5.x. I doubt ntpd is allowed
to write to /etc/ntp, especially if SELinux is enabled.
Have you tried shutting down ntpd and relaunching it manually with the
"don't fork and give me lots of debugging output" switches (-n -ddd)
enabled?
Alternatively (or additionally), you might try wrapping ntpd in strace
to see if any system calls are being thwarted.
