Selenium driver is not responding properly when doing parallel execution inside docker container

I am executing my tests in parallel mode inside docker container, getting “WebDriver Exception: Driver is not reachable” issue for some scenarios. Please note that currently I am launching around 6 driver instances at a time and facing this issue.

As driver is not responding properly hence the screenshot also not getting captured, getting “unable to take screenshot” message. When same thing I tried executing in sequential manner then my execution is happening properly.

Please find the attached screenshot.
