What is paranoia mode in nscd?

This variable can be used in nscd.conf file if you wish nscd daemon to restart itself after a provided amount of time interval. This argument is used in combination with "restart-interval"

Open nscd.conf in edit mode
# vi /etc/nscd.conf
# enable paranoia for One NDS for 1h restart interval
        paranoia                yes
        restart-interval        3600
Here as per my configuration nscd daemon will be restarted automatically by default every hour.
