No "shutdown" message is sent when the service is stopped

[gissahh]

Description

I have a service that should do some cleanup before stopping.

This way runs successful:

1. pm2 is running as service
2. in an admin console I start the service with pm2 start service.js --kill-timeout 10000 --shutdown-with-message
3. in the admin console I enter manually pm2 stop all
4. the service received successfully the shutdown message

But if instead of point 4 I stop the service with net stop pm2.exe, no message is sent to my service.

In the service I use this to catch the message:

process.on('message', msg => {
    if (msg === 'shutdown') {
        console.log('shutdown');
    }
});

Is there another way to do this?
