[🐛 Bug]: Memory leaks on Selenium Hub and enabled CDP

[IlyaUk]

What happened?

An attempt to run tests that use CDP for files download on remote machine via Selenium Hub (hub and nodes are on the same machine) shows a problem with memory leak on Hub side. As a result test run (around 200 tests and about 10 tests that use CDP) fails with the following exception:
Response code 500. Message: session not created: DevToolsActivePort file doesn't exist
After that Docker stops the Hub container with OutOfMemory exception.
If we dive deep into Selenium server thread dump then we see the following:
About 16132 threads open with stacktrace:

  at java.lang.Thread.run(java.base@17.0.11/Unknown Source)

The only one workaround to avoid the issue - set Selenium flag --enable-cdp false for Chrome nodes and disable all tests that use CDP features.

If the issue is valid but there is no time to troubleshoot it, consider adding the help wanted label.

If the issue requires changes or fixes from an external project (e.g., ChromeDriver, GeckoDriver, MSEdgeDriver, W3C), add the applicable G-* label, and it will provide the correct link and auto-close the issue.

After troubleshooting the issue, please add the R-awaiting answer label.

Thank you!

This is the recommended method for downloads: https://www.selenium.dev/documentation/grid/configuration/cli_options/#enabling-managed-downloads-by-the-node.

However, this is not a tool to download massive files. It is a use case in automation, but it does not cover all situations.

You might try to give more memory to the Hub and adjust it to your use case. Memory will be released when the GC passes, but it is also possible that the size of the file is big enough to exhaust the memory available.

Hi @diemol,
Thanks for the advice with --enable-managed-downloads true option. This option is enabled in my Selenium configuration.
The above described problem can not be resolved by memory increase. I gave more than 4Gb for Hub and still no effect. Also I don't try to download large files. Each of my 10 tests that use CDP downloads a file with size around 10-50 Kb. And in general the problem with CDP is not with files download only. An attempt to use CDP for request interceptions also shows problems with memory consumption on Linux machine. But I have only one such case so the negative trend with memory is not so noticeable.

We need a way to reproduce the issue.

Hi, @IlyaUk.
Please follow the issue template, we need more information to reproduce the issue.

Either a complete code snippet and URL/HTML (if more than one file is needed, provide a GitHub repo and instructions to run the code), the specific versions used, or a more detailed description to help us understand the issue.

Note: If you cannot share your code and URL/HTML, any complete code snippet and URL/HTML that reproduces the issue is good enough.

Reply to this issue when all information is provided, thank you.

We need a way to reproduce the issue.

Hi @diemol,
I sent an invitation to my project (JavaProject) with small test that reproduces the problem. Docker compose file was previously attached to the issue.

Hello,
Same problem here (same version of Selenium, same stacktrace in Hub logs).
Tests run during ~20 min on a grid of 8 Firefox nodes, errors start to occur near the end of job.

For me, disabling the VNC client help :

SE_START_VNC: "false"

[joerg1985]

The DriverServiceSessionFactory is not closing the HttpClient when the session fails to start, will fix this the next days.

[joerg1985]

SeleniumHQ/selenium@97d56d0 is the promised commit @IlyaUk could you update to the next nightly and check?

@IlyaUk @EvgenyMarchuk i have done some fixed related releasing the websocket in SeleniumHQ/selenium@ed3edee, SeleniumHQ/selenium@5bac479 and SeleniumHQ/selenium@7612405.

I hope the leak is gone now, could you check this?
