I run a script every minute on my firewalls that calls "ntpq -p" on my 
internal ntpd servers to detect failures and re-route the trafic 
accordingly. This generates a lot of hits.

New users who runs ntpq or ntpdc, etc.  manually often to get to know 
their system better also generate a lot of hits.

I would say make sure no human or script is generating those hits (quite 
high I know). I don't know, maybe use lsof (along with the client socket 
number) or authd if posible at all with ntpd to find out at least which 
user is causing those hits.

Otherwise, you may be facing a hard time trying to configure ntpd properly 
to find out in the end that a script or human somewhere was causing those 
hits. It doesn't mean you can't try to fix ntpd config quickly before 
further investigations.

Bottom line: do not worry to much about internal hits, they do not require 
any ISP bandwidth nor any important resources on your machine ;-)
