[🐛 Bug]: A fatal error has been detected by the Java Runtime Environment

[KiithNabaal]

What happened?

I get strange intermittent errors from a Rust server I have deployed on a Microsoft Azure Container App, which connects to a Selenium standalone-chrome container (also on an Azure container app) to do some web automation. Specifically, the Rust server will say it cannot connect to the standalone-chrome container with no indication as to what the problem is. I ran an experiment locally to see if I can reproduce the issue, and while viewing the container's run output in Docker Desktop it reported (truncated, see logs below):

2025-02-05 16:52:31 #
2025-02-05 16:52:31 # A fatal error has been detected by the Java Runtime Environment:
2025-02-05 16:52:31 #
2025-02-05 16:52:31 # SIGSEGV (0xb) at pc=0x00007ffffe936333, pid=58, tid=154

which terminated the Selenium connection I had. I didn't do anything other than try to establish a connection and it immediately crashed. This doesn't happen all of the time; only seemingly randomly... but it does feel like this happens on a first run, and is a bit smoother afterwards. So ex: it crashes, I restart the container and try to connect again, and then it works.

I also checked the logs for the container running Selenium standalone-chrome, but don't see the same output as above, although I am not sure if that would be caught by Azure? My laptop has significantly more resources than what we allocate to any Azure container.

I understand the error may not be fixable by Selenium devs, but was hoping maybe other people have seen this or any pointers on how to proceed?

Any help is appreciated.

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

docker pull --platform linux/x86_64 selenium/standalone-chrome:131.0

Then opened up Docker Desktop and:
Images > click on selenium/standalone-chrome > run > mapped port 4444:4444 (so I could view the dashboard) and container name to "chromedriver"

Can you have a try with this image selenium/standalone-chrome:nightly?

[KiithNabaal]

This is looking pretty good so far. Ran my test like eight times, including multiple container restarts and so far it has been running well! I will be hopping off in a moment, but next I will upload this to Azure and run a few more tests.

Thanks!

[VietND96]

A difference in that image is using JDK21 instead of JDK17 in the released image. I think you can use this image temporary for a while before the next deployment.

[KiithNabaal]

So I was able to run nightly on Azure and sadly this doesn't seem to have resolved my connection issues. I was able to look at the log stream and it seems that I am getting a WebDriverException. Since that is a separate problem, I will create a separate ticket. Thanks again!
