From the error message, it is trying to do reverse lookup for IP address to DNS name.

if you are using DNS, then add PTR record to your DNS. Please see:

https://www.centos.org/docs/5/html/Deployment_Guide-en-US/s1-bind-zone.html

If not using dns, then add line to /etc/hosts file for the IP and map to host name.

Solution was through correcting name resolution problem on thé Linux.
It seems that NetWorker client is very sensitive to name resolution on Clients.

Simply issuing hostname HOSTNAME command resolved the issue...!!!
