Active handles in the simple Nodejs Request keeps increasing exponentially

问题

I have written a simple node API whose sole purpose is just to notify the user that the internet is alive. I am hitting this API after every 3 seconds and it works fine till the active handles are around 4000 or less but after then my server stops responding till the time I restart the server. I am running this server through pm2. I have attached a link to the image of my server when I type "pm2 monit".Link - https://i.stack.imgur.com/zEgUd.png

const express = require('express');
        const app = express();
        app.get('/users', (req, res) => {
            res.set("Connection", "close");
            res.send({status:200, message:'request received'}).end();
        });

        app.listen(5005, () => {
          console.log('Listening on port 5005');
        });
