no 'masters' statement for non-master zone??

[Support]

Hello, I have 2 name servers up and running, BIND 8.2.2P-3 on RedHat
Linux 6.1,
Machines are both Pentium II's at 350mhz with 64mb ram,

The problems appear when named starts,
both machines are primary nameservers for there respective zones
and slave nameservers for reverse zones in case 1 server drops, the
other server handles the DNS.

Below here is a copy or the errors from my logs, with added comments
from me =)

Nov 23 15:34:44 ns named[5635]: master zone "0.0.127.in-addr.arpa" (IN)
loaded (serial 1999102802)
Nov 23 15:34:44 ns named[5635]: master zone "67.92.204.in-addr.arpa"
(IN) loaded (serial 1999102801)
Nov 23 15:34:44 ns named[5635]: master zone "netonduty.com" (IN) loaded
(serial 1999102305)
Nov 23 15:34:44 ns named[5635]: primary/sanandsan.com:8: data
"ns.netonduty.com" outside zone "sanandsan.com" (ignored)
in the sanandsan.com zone file I have "IN     NS    ns.netonduty.com"
because netonduty is the nameserver, sanandsan.com is a virtual host.

Nov 23 15:34:44 ns named[5635]: master zone "sanandsan.com" (IN) loaded
(serial 1999102306)
Appears to have loaded ok, besides the error above, and the dns works.

Nov 23 15:34:44 ns named[5635]: no 'masters' statement for non-master
zone 'excelserv.com'
Nov 23 15:34:44 ns named[5635]: zone 'excelserv.com' did not validate,
skipping
Nov 23 15:34:44 ns named[5635]: no 'masters' statement for non-master
zone 'excelserv.net'
Nov 23 15:34:44 ns named[5635]: zone 'excelserv.net' did not validate,
skipping
These are the slave servers, as stated in named.conf, not to sure what a
"masters statement" is.

Nov 23 15:34:44 ns named[5635]: listening on [127.0.0.1].53 (lo)

Nov 23 15:34:44 ns named[5636]: Ready to answer queries.
Nov 23 15:35:12 ns named[5636]: Sent NOTIFY for "sanandsan.com IN SOA"
(sanandsan.com); 1 NS, 1 A
Nov 23 15:35:15 ns named[5636]: Sent NOTIFY for "netonduty.com IN SOA"
(netonduty.com); 1 NS, 1 A
And it sends the notify's out for the domains.

Could anyone tell me what a masters staement is, and how I can fix the
errors?
The zone files are available if need to help just ask =)
Thanks alot.
