IE & Edge disconnect too often on heavy websites

Are you requesting a feature or reporting a bug?

Bug

What is the current behavior?

IE & Edge disconnect too often on heavy websites

What is the expected behavior?

IE & Edge do not disconnect and execute the complete test suite

How would you reproduce the current behavior (if this is a bug)?

Run the code below, ideally IE & Edge in parallel, with --skip-js-errors flag (because the ads throw errors in the console)

Provide the test code and the tested page URL (if applicable)

Tested page URL:

https://www.gutefrage.net/frage/wann-werden-genossenschaftsanteile-einer--bank-ausgezahlt

Test code

fixture('QDP Shared')
  .page('https://www.gutefrage.net/frage/wann-werden-genossenschaftsanteile-einer--bank-ausgezahlt')

test('Question plate is shown', async t => {
  const questionDetail = Selector('#Question-detail');
  await t.expect(questionDetail.exists).ok();
});

test('Answer plates are shown', async t => {
  const answers = Selector('.Plate.Plate--answer');
  await t.expect(answers.count).gte(1);
});

Note: We usually run other tests prior those and they are OK (they're run against the homepage www.gutefrage.net, where there're no ads)

Specify your

• operating system:
  Windows 10
• testcafe version:
  0.17.2
• node.js version:
  8.9.1

PS. We're also interested how to debug the issue, get more logs or maybe point out relevant code where this could happen. Thanks!

Hello @lustoykov!

Unfortunately, I wasn't able to find something specific to your website. Microsoft browsers, especially IE, are known for memory leaks in large JS scripts. It can cause browser crashes and hangs. We have an issue to restart browsert that became unresponsive: #1815, you can vote for it to show its importance and promote it for next development iteration

I'm closing this since there were no activity here for a long time. Feel free to reopen the issue if it's still needed.
Also, you can try to run your tests on the latest TestCafe version.
