All, SELinux was enabled (DOH!) and has been now disabled. Didn't fix my problem though. Thanks for that Clint, I don't know HOW many times SELinux has bitten me. Should know by now.
I ran the strace as suggested by Justin and saw THIS little tidbit flash by: 11769 execve("/bin/sh", ["sh", "-c", "/usr/lib/nagios/plugins/check_dig -H 142.166.86.18 -l www.xplornet.com -a 142.166.86.46 -w 0.5 -c 1 -t 5"], [/* 189 vars */]) = -1 E2BIG (Argument list too long) 11751 --- {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=11769, si_status=127, si_utime=0, si_stime=0} (Child exited) -- Argument list too long???? So, SOMETHING (I suspect the shell) doesn't like that many arguments passed. Well, making progress. By the way, this is a bone stock OS install (Fedora 15 currently) and I haven't tweaked anything. Cheers all!
