I would think named-checkzone would complain, but are you missing a new line after the last NS record?

Dear List,

Please help me out to investigate the below scenario .

I have one domain "example.com<http://example.com/>"

$TTL 300
@       IN      SOA     ns4.example.com<http://ns4.example.com/>. postmaster.example.com<http://postmaster.example.com/>. (

  2011110806      ; Serial Number
                                10800           ; Refresh after 3 hours
                                3600            ; Retry after 1 hour
                                604800          ; Expire after 1 week
                                300 )         ; Minimum TTL of 1 day
; Name servers
        IN      NS      ns4.example.com<http://ns4.example.com/>.
        IN      NS      ns2.example.com<http://ns2.example.com/>.
        IN      NS      ns1.example.com<http://ns1.example.com/>.

        IN    A    203.39.45.19
        IN    MX    mail.goole.com<http://mail.goole.com/>.
www        IN    CNAME    example.com<http://example.com/>.
a        IN    A    203.39.45.20
b        IN    A    203.39.45.21
test    IN    NS    ns1973.hostgator.com<http://ns1973.hostgator.com/>.
test    IN    NS    ns1974.hostgator.com<http://ns1974.hostgator.com/>.

named-checkzone  example.com<http://example.com> named.example.com.forward < No Error


The moment I have done the "rndc reload example.com<http://example.com/>", the domain and all subdomain were became not resolvable.

After commenting out below entries & rndc reload , all back to normal.
;test    IN    NS    ns1973.hostgator.com<http://ns1973.hostgator.com/>.
;test    IN    NS    ns1974.hostgator.com<http://ns1974.hostgator.com/>.

Please help me out on this issue.
