    Team:

    Today we ran into an issue..A script (run a /sbin/sh)
    took 100% CPU on out prod system. This script runs as
    cron and updates the .rhosts file (we need this file).
    There was a for loop inside the script which performs
    nslookup (which i think never returned anything). My
    question is
    1. should this script be run in /sbin/sh and what are
    the negative effects of that?
    2. I think it was running the nslookup command to get
    the full hostname with domain info. Is it a good idea
    to run nslookup inside a for loop. If there is an
    issue in getng the info wont it go around? what are
    the best way to pickup a full hostname with domain
    info in that case?

    Please advise.

    Thanks

    Joe.
