Marionette error: Socket timeout reading Marionette handshake data

[Arthi Vigneshwari]

Hi All,

Please help me in understanding why below error occurs and how can I resolve this. Due to this error , tests dint run and pass percentage is not good.

Issue:

Around 15 tests passed in a class and then this error occurred while trying to launch firefox for 16th test. This count is not consistent. In another run, after 8 tests passed, this error occurred while trying to launch firefox for 9th test. After this error occurred, the following tests dint run and failed at this point.

Selenium : 3.14

Firefox : 60.0

Geckodriver:0.20.0

I searched about this error and got an info that if firefox launched by previous tests are not closed properly, we hit this error. But firefox launched by previous tests have closed gracefully.Still this error occurs. 

Error Message

org.openqa.selenium.WebDriverException: Socket timeout reading Marionette handshake data: Resource temporarily unavailable (os error 11)

Try upgrading geckodriver and Firefox with some latest versions of each.
