Solaris Performance
Dear All,

I have Sun OS 5.10 Solaris OS running.
Code:
SunOS **** 5.10 Generic_118833-36 sun4v sparc SUNW,Sun-Fire-T200

++There is a process named nscd utilizing high cpu not 100 though. Due to this the printer are delayed in printing and retreving information from this server
Code:

++Why is it nscd utilizing high resources? When i Kill it, it re-spawns a new nscd process

++When I do truss on the process it checks ipnodes,hosts file and does nothing:
