GNS errors

Hi experts,

I followed to MOS note DNS and DHCP Setup Example for Grid Infrastructure GNS [ID 946452.1] to configure DNS, DHCP for GNS.
Everything working as I expected
[grid@c1n1 ~]$ nslookup itdata-scan.cluster.it.data
Server:         192.168.7.10
Address:        192.168.7.10#53

Non-authoritative answer:
Name:   itdata-scan.cluster.it.data
Address: 192.168.7.110
Name:   itdata-scan.cluster.it.data
Address: 192.168.7.106
Name:   itdata-scan.cluster.it.data
Address: 192.168.7.109
and round robin also works but I don't know why I received many errors in cluster log.
This error repeated every minute.

    CLSGN-00178: Resolution of name "string" failed.
    Cause:     Check to make sure that an address for the name has been registered with GNS. If it is configured, check to make sure that DNS has been properly configured.
    Action:     GNS failed to retrieve the address of the specified name.

    can you please past the output of below

    host itdata-scan.cluster.it.data

    Thanks for reply.
    Strange behavior.

    First time

    [grid@c1n1 ~]$ host itdata-scan.cluster.it.data
    itdata-scan.cluster.it.data has address 192.168.7.106
    itdata-scan.cluster.it.data has address 192.168.7.109
    itdata-scan.cluster.it.data has address 192.168.7.110
    Host itdata-scan.cluster.it.data not found: 3(NXDOMAIN)
    Host itdata-scan.cluster.it.data not found: 3(NXDOMAIN)

    after few seconds

    [grid@c1n1 ~]$ host itdata-scan.cluster.it.data
    Host itdata-scan.cluster.it.data not found: 3(NXDOMAIN)


    Something wrong in DNS ?

    [grid@c1n1 ~]$ srvctl status gns
    GNS is running on node c1n2.
    GNS is enabled on node c1n2.

    SCAN VIP name: scan3, IP: /itdata-scan.cluster.it.data/192.168.7.106
    [grid@c1n1 ~]$

    Any ideas ?

    Here DNS log
    DNS format error from 192.168.7.150#53 resolving itdata-scan.cluster.it.data.cluster.it.data/A for client 192.168.7.11#18794: too many questions
    Why domain name repeated ? I mean must be itdata-scan.cluster.it.data not itdata-scan.cluster.it.data.cluster.it.data

    What I investigated is really interesting.

    After DNS service restart bind able to resolve scan name but only once........
    before restart
    ----
    [root@nc1 ~]# host itdata-scan.cluster.it.data
    Host itdata-scan.cluster.it.data.cluster.it.data not found: 2(SERVFAIL)
    
    [root@nc1 ~]# /etc/init.d/named restart
    
    after restart
    -----
    [root@nc1 ~]# host itdata-scan.cluster.it.data
    itdata-scan.cluster.it.data has address 192.168.7.110
    itdata-scan.cluster.it.data has address 192.168.7.106
    itdata-scan.cluster.it.data has address 192.168.7.109
    Host itdata-scan.cluster.it.data.cluster.it.data not found: 2(SERVFAIL)
    Host itdata-scan.cluster.it.data.cluster.it.data not found: 2(SERVFAIL)
    
    
    [root@nc1 ~]# host itdata-scan.cluster.it.data
    Host itdata-scan.cluster.it.data.cluster.it.data not found: 2(SERVFAIL)
    Please who already faced with situation like this suggest ?
