[🐛 Bug]: version 4.10 java.util.concurrent.TimeoutException #1903

atranou · 2023-07-28T12:39:19Z

What happened?

Hello,

We recently upgraded to 4.10 version (selenium hub - selenium node chrome - selenium node firefox )
but we are getting the following error: selenium.common.exceptions.TimeoutException: Message: Unable to execute a request for an existing session: java.util.concurrent.TimeoutException.
Our setup is in the section: Command used to start Selenium Grid with Docker

In our running process, we open more than one selenium sessions on the same domain that they run concurrently.
This error doesn't always emerge, but it appears some and there.
Appears both on a Chrome session or on a Firefox session.

Is this a bug or something?
In case you need extra info in order to reproduce, I am kindly asking you to help me a bit with what exactly is important to you.

Thank you a lot!

Triage this issue by using labels.

If information is missing, add a helpful comment and then I-issue-template label.

If the issue is a question, add the I-question label.

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 usually happens when trying to run more concurrent sessions than the number of available slots in the Grid. They get queued, and then time out.

I will leave some links below so you can ask more questions and debug the situation.

Hello thanks a lot for your comment!
I forgot to mention that I am pretty sure that there were available slots in the grid when these errors emerge
(the concurrency is around 50% all the time)

In our logs there is a http status 500
Does this mean that Firefox gets a 500 response could this ends up to timeout somehow?

diemol · 2023-07-28T15:01:26Z

That timeout means that the browser could not load the URL, it timed out.

For more questions please use the links above. It is really hard to keep track here.
