Thanks for providing your input and suggestion. I shall try and get back to you.
No even after updating the rules and policies, the error remains the same.
Please check the error messages under the /var/log/messages file. you might get the idea that why the services are not starting.
Thanks for your suggestion however this problem has been resolved and the root cause for this problem is "NetFlow Port" was not defined. After the NetFlow Port has been defined/enabled the service started working.
Appreciate the help and suggestions provided by each of you.
It has nothing to do with a rule set, what I would do first is to restart service via this NitroStop --nod this will not return a prompt until it returns. After prompt returns NitroStart --nod and when the prompt the returns try your NitroStarted again. You can search for the process via:
lmk and I will help further
