mysql not runing by ctlscript checking, but the redmine service is ok?

I installed the Bitnami as root on osx lion, and add 2 plist files to /Library/LaunchDaemon as Native Installers Quick Start Guide said.

Right now I use the ctlscript.sh to check the service runnig, there is strange things.

subversion not running
apache already running
mysql not running

But I can login to redmine and phpmyadmin, then ps aux | grep mysql

Why the ctlscript check status is different with the real using?
