CI fails due to Chromium Renderer process crashes on Cypress Cloud

[luixxiul]

Steps to reproduce

https://cloud.cypress.io/projects/ppvnzg/runs/12024/specs shows that a couple of the tests have failed as the Chromium Renderer process crashed. Here is the log displayed on the page above.

Incomplete

    We detected that the Chromium Renderer process just crashed.

    This is the equivalent to seeing the 'sad face' when Chrome dies.

    This can happen for a number of different reasons:

    - You wrote an endless loop and you must fix your own code
    - You are running Docker (there is an easy fix for this: see link below)
    - You are running lots of tests on a memory intense application.
        - Try enabling experimentalMemoryManagement in your config file.
        - Try lowering numTestsKeptInMemory in your config file.
    - You are running in a memory starved VM environment.
        - Try enabling experimentalMemoryManagement in your config file.
        - Try lowering numTestsKeptInMemory in your config file.
    - There are problems with your GPU / GPU drivers
    - There are browser bugs in Chromium

2 of 42 specs skipped

https://cloud.cypress.io/projects/ppvnzg/runs/12026/specs shows the same error as well.

I am not sure how to reproduce the error consistently on Cypress Cloud, while I notice the same issue often happens on a local machine with 6GB RAM when it runs timeline.spec.ts tests.

Maybe related to element-hq/element-desktop#680?

Outcome

What did you expect?

The test should complete.

What happened instead?

The test was incomplete due to the issue described above.

Operating system

No response

Browser information

Will you send logs?

No

I suspect this kind of issue would happen more frequently once we have added more E2E tests.

Here is another case: https://cloud.cypress.io/projects/ppvnzg/runs/12167/specs (for matrix-org/matrix-react-sdk#10512)

Also: https://cloud.cypress.io/projects/ppvnzg/runs/12178/specs (matrix-org/matrix-react-sdk#10544 (comment)), https://cloud.cypress.io/projects/ppvnzg/runs/12180/specs

I have not noticed a similar issue recently. I am going to close this for now. Will reopen if I started seeing the issue again.
