The -v test is not entirely representative of the normal running
situation (mainly because it doesn't change uid/gid to nagios). The
service nagios restart (or /etc/rc.d/init.d/nagios restart) does the
testing as the nagios user and gives better diagnostics as to what is
going wrong without having to resort to strace. Just remember that
restart does a poor job of stopping nagios so in a production environment
after changing configs I do a stop, then a killall to clear up the
stragglers then do a restart to get a check of the config.

Ownership/permissions of parent directory? SELinux complications?
