Graceful shutdown with nodejs pm2 SIGINT not working

问题

Hello I Have an application server written in js and is running on windows. Furthermore I'm using pm2 module but I have noticed that when I start my application server via pm2 start index.js -i 8 and then I want to stop all pm2 processes via pm2 stop all the event listeners for SIGINT are completely ignored...

I should add that this works fine when used with plain node and not pm2. So I was wondering am I missing something obvious here? Bellow is a sample test source and pm2 docs

const http = require('http'); 
const port = 3000

const requestHandler = (request, response) => {
    response.end('Hello Node.js Server!'); 
}

const server = http.createServer(requestHandler);

server.listen(port, (err) => {
    if (err) {
        console.error(err);
    } else {
        console.log(`server is listening on ${port}`);
    } 
});

process.on('SIGINT', () => {

    console.log('NIX SIGINT!!!');

    process.exit(0);

});

process.on('message', (msg) => {

    if (msg == 'shutdown') {

            console.log('WIN SIGINT!!!');

            process.exit(0)

    } else {
        console.log('msg:', msg);
    }

});

Update:

Versions & OS

OS: Windows

pm2 version: ^4.2.1
