My guess is that `service flexlm status' is returning
exit code 0 even if the service is not running.
Manually check the exit code while it's stopped.
$?==0 means the service is deemed good by rgmanager.

I hacked together an init script for our flexlm server,
and I've just posted it at:

  https://gist.github.com/1296847

In the comments of the script, I point out the importance
of error codes and provide URL references to LSB compliance
notes. The comments also mention how to override the script variables
(in /etc/sysconfig/flexlm).

Feel free to critique the init script.
