I am using an open source project (Traccar) and they provide a rc script to start and stop the service https://www.traccar.org/freebsd/
This script doesn't work, I can easily start the server if I do:
However, I want to have this application handled by FreeBSD, so I wrote a custom rc.d script:
Now, this script starts the service, and correctly starts it when the machine is powered on.
However, it doesn't show as running...
So I check the output of the PID files:
And if I can see those PID's here:
And if I run kill on 50137 (the java process, which is also the same number returned from /var/run/traccar.pid) the deamon correctly brings it back up.
So my new script *half* works, it brings the application up, but doesn't show it as running from the service command, and because of this I cannot use
Where as above, we know the PID returned from /var/run/traccar_daemon.pid is running and shows from ps output.
I think I am almost there, if anyone can help/advise what might be wrong, I would be very grateful, thanks.
This script doesn't work, I can easily start the server if I do:

# java -jar tracker-server.jar conf/traccar.xml &However, I want to have this application handled by FreeBSD, so I wrote a custom rc.d script:
