Puppeteer doesn't close browser

Question

I\'m running puppeteer on express/node/ubuntu as follow:

var puppeteer = require(\'puppeteer\');
var express = require(\'express\');
var router = express.Router(

From my experience, the browser closing process may take some time after close is called. Anyway, you can check the browser process property to check if it's still not closed and force kill it.

if (browser && browser.process() != null) browser.process().kill('SIGINT');

I'm also posting the full code of my puppeteer resources manager below. Take a look at bw.on('disconnected', async () => {

const puppeteer = require('puppeteer-extra')
const randomUseragent = require('random-useragent');
const StealthPlugin = require('puppeteer-extra-plugin-stealth')

const USER_AGENT = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.75 Safari/537.36';
puppeteer.use(StealthPlugin())

function ResourceManager(loadImages) {
    let browser = null;
    const _this = this;
    let retries = 0;
    let isReleased = false;

    this.init = async () => {
        isReleased = false;
        retries = 0;
        browser = await runBrowser();
    };

    this.release = async () => {
        isReleased = true;
        if (browser) await browser.close();
    }

    this.createPage = async (url) => {
        if (!browser) browser = await runBrowser();
        return await createPage(browser,url);
    }

    async function runBrowser () {
        const bw = await puppeteer.launch({
            headless: true,
            devtools: false,
            ignoreHTTPSErrors: true,
            slowMo: 0,
            args: ['--disable-gpu','--no-sandbox','--no-zygote','--disable-setuid-sandbox','--disable-accelerated-2d-canvas','--disable-dev-shm-usage', "--proxy-server='direct://'", "--proxy-bypass-list=*"]
        });

        bw.on('disconnected', async () => {
            if (isReleased) return;
            console.log("BROWSER CRASH");
            if (retries <= 3) {
                retries += 1;
                if (browser && browser.process() != null) browser.process().kill('SIGINT');
                await _this.init();
            } else {
                throw "===================== BROWSER crashed more than 3 times";
            }
        });

        return bw;
    }

    async function createPage (browser,url) {
        const userAgent = randomUseragent.getRandom();
        const UA = userAgent || USER_AGENT;
        const page = await browser.newPage();
        await page.setViewport({
            width: 1920 + Math.floor(Math.random() * 100),
            height: 3000 + Math.floor(Math.random() * 100),
            deviceScaleFactor: 1,

                    req.abort();
                } else {
                    req.continue();
                }
            });
        }

        await page.evaluateOnNewDocument(() => {

            const originalQuery = window.navigator.permissions.query;
            return window.navigator.permissions.query = (parameters) => (
                parameters.name === 'notifications' ?
                    Promise.resolve({ state: Notification.permission }) :
                    originalQuery(parameters)
            );
        });

        await page.evaluateOnNewDocument(() => {
            // Overwrite the `plugins` property to use a custom getter.
            Object.defineProperty(navigator, 'plugins', {
                // This just needs to have `length > 0` for the current test,
                // but we could mock the plugins too if necessary.
                get: () => [1, 2, 3, 4, 5],
            });
        });

        await page.evaluateOnNewDocument(() => {

            Object.defineProperty(navigator, 'languages', {
