Please have a look at the wikipage
and change your initscripts to comply with the LSB standard.
Especially check the exit status and add a LSB Header.
E.g. starting a service should return with 0, if the service is already running and stopping a stopped service should also return with 0.
Also check, if your service has to be _on_ per default, and turn it off in the old chkconfig line, if not.
