5.2.45 and up: org.openqa.selenium.WebDriverException: disconnected: not connected to DevTools about hsac-fitnesse-fixtures HOT 2 OPEN

I have not experienced this myself. What I saw in the past with strange unreproducible errors at random points in a test suite was that the docker container ran out of memory. Do you have any memory limits on the container? Can you monitor RAM usage during a test run?

Do you have the same error not running headless, not providing a profile (I believe the images also have a window manager so should support that)

On GitHub I saw SeleniumHQ/selenium#11809 (comment), which also reports inconsistent errors of this type

I found one answer on StackOverflow that might be related, but you are on Linux. https://stackoverflow.com/questions/59847431/org-openqa-selenium-webdriverexception-disconnected-not-connected-to-devtools#answer-77319083

from hsac-fitnesse-fixtures.

Tried a few things:

• Run with --headless=new (previously we didn't run headless).
• Set a memory limit of 8GB (previously no limit, and machines we run on do not seem to come close to memory limits).

Issue still occurs with 5.3.7.
