Running backstopjs in digitalocean jenkins

Hey,

I have this issue that's really hard to debug, when i run the "test" or "reference" command of backstopjs in jenkins via shell it would run at first then after few seconds of running it would hang up then jenkins would be down and you will have to restart jenkins via ssh to make it work again.

Have tested the same script and setup in my local and it works fine, also tested npm run commands directly in ssh of the my digitalocean droplet and it would run fine.

Do you have any idea on this? Thank you
