What is "Page crashed!" error?

[gajus]

Steps to reproduce

N/A (Not able to reproduce consistently.)

Tell us about your environment:

• Puppeteer version: master
• Platform / OS version: Docker image based on Node:8.5 https://gist.github.com/gajus/3426d738dde10ce3c9a9bb39138578ea
• URLs (if applicable): https://www.myvue.com/

What steps will reproduce the problem?

Please include code that reproduces the issue.

const defaultPuppeteerOptions: Object = {
  args: [
    '--no-sandbox',
    '--disable-setuid-sandbox'
  ],
  devtools: false,
  headless: true,
  ignoreHTTPSErrors: true,
  slowMo: 0
};

const defaultViewport = {
  deviceScaleFactor: 1,
  hasTouch: false,
  height: 1024,
  isLandscape: false,
  isMobile: false,
  width: 1280
};

const browser = await puppeteer.launch({
  ...defaultPuppeteerOptions
});

const page = await browser.newPage();

await page.setViewport(defaultViewport);

await page.goto('https://www.myvue.com/');

What is the expected result?

No error.

What happens instead?

I am intermittently getting "Page crashed!" error.

What does the error mean?

[gajus]

I cannot replicate this issue outside of Docker.

[ebidel]

There's an example Docker setup and tips and tricks when hitting issues like this in https://github.com/GoogleChrome/puppeteer/blob/master/docs/troubleshooting.md#running-puppeteer-in-docker.

[gajus]

That answer did not explain what the error means.

For anyone running into this issue on K8S, the issue is that /dev/shm allocation is too small (64MB default).

You cannot override Docker shm configuration in K8S, however, there is this workaround https://stackoverflow.com/a/46434614/368691.

This worked

By default, Docker runs a container with a /dev/shm shared memory space 64MB.
 This is typically too small for Chrome and will cause Chrome to crash when rendering large pages. 
To fix, run the container with docker run --shm-size=1gb to increase the size of /dev/shm. 
Since Chrome 65, this is no longer necessary. 
Instead, launch the browser with the --disable-dev-shm-usage flag:

const browser = await puppeteer.launch({
  args: ['--disable-dev-shm-usage']
});

I met this on Ubuntu 16.04 (no docker)

[rotimi-best]

I still had this Error: Page crashed with '--disable-dev-shm-usage' on Ubuntu 16.04 even with

const browser = await puppeteer.launch({ args: ['--no-sandbox', '--disable-dev-shm-usage'] });

I solve my issue already. The problem was that there wasn't enough memory in my VM so it kept giving me this error. Kill all unnecessary processes and running puppeteer one more time did the trick.

[voxsoftware]

have the same issue, the question here is why is an unhandled promise rejection? How can I catch that error? because looks that normal try catch not working
