[🐛 Bug]: Xvfb and VNC crash under M1 Mac when using AMD64 image

[slhck]

What happened?

I am running the standalone Chrome Docker image to run some tests against. The first test always works fine, but any subsequent tests fail with an error:

session not created: DevToolsActivePort file doesn't exist

My test consists of a simple set of steps:

let builder: webdriver.Builder;
const chromeOptions = new chrome.Options().addArguments(
        '--no-sandbox',
        '--disable-setuid-sandbox',
        '--disable-dev-shm-usage',
        '--mute-audio',
        '--disable-web-security',
        '--autoplay-policy=no-user-gesture-required',
        '--safebrowsing-disable-download-protection',
      );
builder = new webdriver.Builder()
        .forBrowser('chrome')
        .usingServer(process.env.SELENIUM_HUB_URL)
        .setChromeOptions(chromeOptions)
const driver = await driver.get('https://www.google.com');
const title = await driver.getTitle();
await driver.quit();
await driver.close();

When I run the test once, all is fine. The second time I run it, it errors out.

Command used to start Selenium Grid with Docker (or Kubernetes)

docker run --platform linux/amd64 -p 4444:4444 -p 7900:7900 --shm-size="2g" selenium/standalone-chrome:126.0-20240621

This issue has been reported several times. Please check the comments of the reports history and if you are still facing it after trying out the different suggestions, report it to the Chrome folks.

Hi, @slhck.
This issue has been determined to require fixes in ChromeDriver.

You can see if the feature is passing in the Web Platform Tests.

If it is something new, please create an issue with the ChromeDriver team.
Feel free to comment the issues that you raise back in this issue. Thank you.

[slhck]

Thanks for the quick answer, and sorry, I somehow didn't see those. Based on my Internet searches most issues had to do with the --no-sandbox flag.

Can you please let me know which specific solution from these other issues you had in mind? Because you are of course right about the same error message, and quick to close the issue, yet the problem is only occurring after a first successful test. It's not like this issue is exhibited from the first startup.

Specifically, after the first session is stopped, I see:

2024-07-08 11:02:59,770 INFO exited: xvfb (exit status 1; not expected)
11:02:59.833 INFO [LocalSessionMap.lambda$new$0] - Deleted session from local Session Map, Id: 28b8c47fdb3c8e0940b305076c94d370
11:02:59.834 INFO [GridModel.release] - Releasing slot for session id 28b8c47fdb3c8e0940b305076c94d370
11:02:59.835 INFO [SessionSlot.stop] - Stopping session 28b8c47fdb3c8e0940b305076c94d370
2024-07-08 11:02:59,937 INFO exited: vnc (exit status 133; not expected)

If indeed XVFB is not running, I would expect Chrome not being able to even launch. So this seems to be a different issue than the other ones — just the same final error message.

More specifically:

• [🐛 Bug]: DevToolsActivePort file doesn't exist #2164 ends with a different error. XVFB is not stopped here.
• [🐛 Bug]: session not created: DevToolsActivePort file doesn't exist - Error occurred for launching Windows Touch Shell.  #2130 has been locked without a response
• Per [🐛 Bug]: standalone-chrome crashes when creating a new session (unknown error: DevToolsActivePort file doesn't exist) #1625, it is pointing to another platform; this is not relevant for my use case as I'm just emulating Linux/amd64.
• [🐛 Bug]: selenium grid [4.2.1-20220531]: edge node - DevToolsActivePort file doesn't exist #1596 was solved without an apparent change needed
• Chrome standalone doesn't come up sporadically #952 was closed without a response from the OP
• DevToolsActivePort file doesn't exist when container used by Jenkins ??  #822 was closed without more info from the OP

[diemol]

This one is also giving information about this SeleniumHQ/selenium#14076

[slhck]

What specifically do you mean with respect to the other issue? As far as I can tell the session itself is closed properly in my case, and the resource consumption is normal. It's also just one test, so it's not only occurring with multiple parallel executions like the OP mentioned. The underlying reason seems to be the VNC and XVFB session crashing. What could cause that?

I have also tried with more shared memory (4G) but that did not help.

[diemol]

What do you see in the XVFB and VNC logs?

https://github.com/SeleniumHQ/docker-selenium/blob/trunk/NodeBase/selenium.conf#L13

[slhck]

When I dump the Xvfb logs during the first test I get:

➜ docker exec zen_wozniak tail -f /var/log/supervisor/xvfb-stdout.log
Failed to read: session.screen0.iconbar.mode

X connection to :99.0 broken (explicit kill or server shutdown).

The "explicit kill or server shutdown" message appears when the test has finished. No subsequent sessions can be started.

I wonder if the supervisord configuration should be changed to restart Xvfb in case of failure? Still, I do not see any explicit calls to kill in this repository.

[diemol]

Are you using a macOS M1/M2/M3?

[slhck]

Yes, I am using a M1 Mac. This is from VNC:

➜ docker exec gallant_morse tail -f /var/log/supervisor/vnc-stdout.log /var/log/supervisor/vnc-stderr.log
==> /var/log/supervisor/vnc-stdout.log <==
Centering wallpaper
Trying to update the open file descriptor limit from 1048576 to 100000.
Successfully updated the open file descriptor limit.

Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?

The scheme stores pixel data offscreen on the VNC viewer side for faster
retrieval.  It should work with any VNC viewer.  Try it by running:

    x11vnc -ncache 10 ...

One can also add -ncache_cr for smooth 'copyrect' window motion.
More info: http://www.karlrunge.com/x11vnc/faq.html#faq-client-caching

caught XIO error:
assertion failed [rem_idx != -1]: Unable to find existing allocation for shared memory segment to unmap
(VMAllocationTracker.cpp:745 remove_shared_mem)

Apparently it's the:

Unable to find existing allocation for shared memory segment to unmap

So apparently running the Linux/AMD64 image itself with Chrome is not possible?

When I run the Chromium image natively, it works:

➜ docker run -p 4444:4444 -p 7900:7900 --shm-size="2g" selenium/standalone-chromium:126.0-20240621
