/usr/sbin/nscd [-f configuration-file][-g][e cachename, yes | no] [-i cachename]
The nscd daemon provides a cache for the most common nameservice requests. It is started up during multiuser boot by the /etc/rc2.d/S76nscd run control script. The default /etc/nscd.conf determines the behavior of the cache daemon. See nscd.conf(4).
nscd provides caching for the passwd(4), group(4), and hosts(4) databases through standard libc interfaces, such as gethostbyname(3N), gethostbyaddr(3N), and others. Each cache has a separate time-to-live for its data; modifying the local database (/etc/hosts, and so forth) invalidates that cache within 10 seconds.
Note
The shadow file is specifically not cached. ...
