Nothing wrong with that. If you ask a daemon to start it will start :)

On top of that, cpglockd is harmless if there is no RRP mode active, or

It tells sysvinit to start cpglockd before rgmanager IF cpglockd is
enabled via chkconfig, otherwise it is not started. That value is used
only to calculate the symlink S* K** values for rc.d/
