I have 1 primary DNS server ( running on Fedora and 2 secondary ones (ns2 and ns3). DNS changes made on my web servers first goes to the primary name server and then propagates to the secondary servers. After making a DNS change on a domain on the web server, I can't see the new dns information on my ns1 when I perform:

dig @ns1 A

I then went to the master records on the names server (uses named) in the directory /var/named/run-root/var/named/masters and I see the A record has been updated appropriately.

Tailing the logs /var/log/messages is not showing any errors. What could be the issue?

if you can't see new info on master then likely after making the change you didn't reload the zone ; try rndc reload and make sure you incremented serial in zone afer the change so slaves pick up the change – Hrvoje Špoljar Oct 15 '12 at 14:34

Have you incremented serial number?
