I don't think you're implying that nagios is causing this. Please  
clarify if you are.

I've never seen nscd use a significant amount of memory. I'd try to  
determine what cache is using it and either tune/limit that cache,  
tune the reason it's being populated so heavily or disable caching of  
that altogether if it's a problem for you. The nscd manpage lists the - 
g option to display current usage stats.
