Execution gets stuck - chromedriver and Katalon processes 0 task manager

Web Testing
1

Hi guys

For several months now, I have been experiencing a slowdown in the execution of tests. I am uncertain why this is occurring, but suddenly ChromeDriver and Katalon Studio become stuck, and the processes in Task Manager remain at 0%. To unblock them, I have to press F11 or F12 in the browser.

*I always use the latest available version of ChromeDriver.
*Katalon Studio Version 9.7.6.
*The project uses CustomKeywords to wait for elements (I ran the test without customKeywords and the same thing happened).
*When using Chrome headless, it works normally.

Hi there, and thanks for posting in the Katalon community! :hugs:

To help you faster, please review our guide on Custom Keyword here: Introduction to custom keywords in Katalon Studio | Katalon Docs. Double-checking the steps and configurations might resolve the issue.

If the doc doesn’t help, feel free to provide more details, and a community member will assist you soon. Thanks for being a part of our community!

Thank you very much for your prompt reply, but I have already seen those guides before

Please check the Error log file (.log) and try to find some information:

is this happening only with 9.7.6 only or latest version too?

No important information is visible in the logs, but after a long time, only this error is displayed in Katalon.

can you forcefully kill chromedriver sessions after each run and see if issue resolves?

same result

I have a doubt that you would have an old version of ChromeDriver running on your machine.

Please show the exact version of ChromeDriver you have.

You can do it in the commandline. For example, on my Windows11, I used the “MINGW64” with bash,

$  pwd
~/Katalon_Studio/Katalon_Studio_Free_Windows_64-9.7.6/configuration/resources/drivers/chromedriver_win32

then I did

$ ./chromedriver.exe -v
ChromeDriver 139.0.7258.154 (9e0d6b2b47ffb17007b713429c9a302f9e43847f-refs/branch-heads/7258@{#2926})

I could see that I have ChromeDriver v139.0.7258.154, which was bundled in the v9.7.6 distributable zip file. v139.0.x is too old. It won’t work with the current version Chrome browser.

I tried to update the ChromeDriver on my machine in the v9.7.6 Free:

I did Tools > Update WebDrivers > Chrome Driver

I checked the version:

$ ./chromedriver.exe -v
ChromeDriver 140.0.7339.207 (17230b545fd18b35aad49122e5af97a463bc7a9c-refs/branch-heads/7339@{#2364})

The ChromeDriver has been updated.

what actions/code you performed to get the same results?

When I say “same result,” I mean that somewhere in the execution it gets stuck, not in a specific action or code. Sometimes it even gets stuck when logging in, it’s quite strange

Please try removing the current installation of Katalon Studio, and re-installing it cleanly.

without looking any logs/versions/errors, it’s really tough to isolate and replicate the issue

In this latest version of Katalon at least it times out; in version 9 it gets stuck
