[ntp:questions] Servers with identical ntp.conf keep falling out of sync

Hey all, I have two servers in two different datacenters using the same
ntp.conf.

To wit:

# Prohibit general access to this service.
restrict default ignore

# Permit all access over the loopback interface.  This could
# be tightened as well, but to do so would effect some of
# the administrative functions.
restrict 127.0.0.1

server 0.us.pool.ntp.org
server 1.us.pool.ntp.org
server 2.us.pool.ntp.org

driftfile /etc/ntp/drift

The problem is, that the servers keep drifting apart from each other,
to the degree that DNS TSIG transactions break down.  Is there anything
obvious to try to fix this?  Usually when this happens, killing ntpd
and then running ntpdate will fix it.
