[🐛 Bug]: WebDriverException and InterruptedExceptions thrown from standalone-chrome on Azure container app

[KiithNabaal]

What happened?

My setup:

• Running Microsoft Azure Container Apps in a single container app environment, with no external/public ingress enabled.
• Running the selenium/standalone-chrome:nightly Docker image on an Azure Container App container with 2 CPU and 4 Gb memory. The container is not always running; a replica (or instance) spins up only when there is work for it to do.
• Running a Rust server also as a container app which connects to the standalone-chrome container to perform web scraping and other Selenium-type tasks.

Chrome capabilities set in Rust:

let mut caps = DesiredCapabilities::chrome();
caps.set_headless()?;
caps.set_disable_web_security()?;
caps.set_ignore_certificate_errors()?;
caps.set_no_sandbox()?;
caps.set_disable_gpu()?;
caps.set_disable_dev_shm_usage()?;

Occasionally my Rust server reports that it is unable to send a request to the standalone-chrome server, which ends further processing on the Rust server. I am able to run standalone-chrome on my laptop in Docker Desktop with no issues, but I get a WebDriverException and java.lang.RuntimeException: java.lang.InterruptedException when I run it on Azure.

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

I dont really know since this runs on Microsoft Azure. I imagine they just do something like docker run.

Relevant log output
