A couple possible problems here...
	- use full paths to every program (lsof, grep, wc). The environment  
available to the script when run by NRPE may not have the $PATH you  
expect.
	- are you sure that lsof is returning results you expect when run by  
a non-root user? From my own testing, running '/usr/sbin/lsof -Pn -i'  
as root returns results but when run as a normal user, nothing is  
returned.

Your script is exiting with an exit code of 3. In the script above you  
always exit with a 0. Why the difference? Under what conditions does  
your script 'exit 3'?
