Regarding the page crash issue in Webdriver

[Arthy Bhoopi]

Hello Everyone!!

Thanks in Advance!!!

Anyone observed a similar kind of issue, any solution for this?

I am facing this issue when build thru Jenkins hosed in CENTOS!! In my local (windows ) i dont get this issue!! 

org.openqa.selenium.WebDriverException: unknown error: session deleted because of page crash from unknown error: cannot determine loading status from tab crashed (Session info: headless chrome=87.0.4280.141)

I am using Webdrivermanager in Pom.xml

<dependency>

    <groupId>io.github.bonigarcia</groupId>

    <artifactId>webdrivermanager</artifactId>

    <version>4.2.2</version>

        </dependency>

With  regards,

Arthy V.

This looks like it is going to be very hard to find.

I suspect that when running in Jenkins it is running headless and on your local machine it is not running headless.  So maybe that is the place to start - investigating the difference in code.

I really can't provide a better answer than that.  I would need all the code to figure it out and a.lot of time.

I did have this error in my tests and it is a little hard to remember why.  It was something like I was calling a step from another step definition which may have been in a different class.

I fixed the issue by removing all calls from one step to another and calling the actual method instead.

So instead of something like:
  [Given(@"(.*) is logged in")] 

  public void GivenIsLoggedIn(string name) 

  { 

       Given(string.Format("the user {0} exists", name)); 

       Given(string.Format("I log in as {0}", name)); 

  }

I replaced with:

  [Given(@"(.*) is logged in")] 

  public void GivenIsLoggedIn(string name) 

  { 

       UserExists(name) 

       LogIn(name); 

  }

However the error you have maybe caused by other odd things.

Goodluck,

Adrian.

Hi

I was getting  below error :

org.openqa.selenium.WebDriverException: unknown error: session deleted because of page crash
from unknown error: cannot determine loading status
from tab crashed

The solution that I got was : 

1. Simpy mount -v /dev/shm:/dev/shm

Or, longer, create a big shm

Started in privileged mode: docker run --privileged
Fix small /dev/shm size
2. I am not sure how it works in that specific environment, but I would double check and make sure that the running container /dev/shm size is at least 2GB (the default size is 64MB). Is there a way for you to do that? Go inside the container and check it, I am sure the EC2 instance has it but I am not sure if the container is actually using it.

"https://github.com/elgalu/docker-selenium/issues/20
https://github.com/SeleniumHQ/docker-selenium/issues/589"

What worked for me :

1. when running in chrome image :

chrome:
     image: selenium/node-chrome-debug:3.141.59-20200409
       #By default, Docker runs a container with a /dev/shm shared memory space 64MB. This is typically too small for Chrome and will cause Chrome to crash when rendering large pages.
       #Since Chrome 65, this is no longer necessary. Instead, launch the browser with the --disable-dev-shm-usage flag:
     volumes:
        - /dev/shm:/dev/shm
        #- /home/ec2-user/workspace/AUTOBOTS_QA_CERTIFICATION/testautomationrunner:/home/seluser/Downloads
        - ${PWD}:/home/seluser/Downloads
    # shm_size: 256mb
     depends_on:
        - selenium-hub

2. In script for chrome driver

options.addArguments("--no-sandbox"); //has to be the very first option , // Bypass OS security model

        options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems

Let me know if it works for you.

Regards

Harsh

To locate my issue, I put log messages in many places.

Then I examined the results to see which message was not logged and then I added even more log messages to narrow the issue down to 1 line of code.

I think this is your best strategy.
