Protractor + xvfb + selenium test Hangs on Jenkins

问题:

I'm having this issue sometimes on my automated tests running remotely on Jenkins. About 30% of the times.

The error:

Tests hangs after this line: "I/launcher - Running 1 instances of WebDriver"

It gets stuck at this step indefinitely and I have to stop execution (manually) or wait to timeout to take control of it.

I tried several known solutions that i found on this site but nothing changed on my results.

My config:

Ubuntu OS 14.04.5 on a headless cloud storage system.

xvfb

Jenkins 1.656

selenium-server-standalone-2.53.1

chromedriver_2.24linux64

geckodriver-v0.9.0

nodejs v0.10.37

node v6.3.1

npm 3.10.3

protractor Version 4.0.9

grunt-cli v1.2.0

grunt v0.4.5

jasmine v2.5.2

jasmine-core v2.5.2

Jenkins Job Config:

Jenkins downloads my test project from github and runs the following commands on Project's shell:

node node_modules/grunt-cli/bin/grunt testName:parameters (I don't want to run grunt globally, thats why i execute it in this way.)

Is there anything i can try in order to solve this hang issue? Thanks in advance!
