Fund: Zombie process killing memory and cpu

I am using Pageres to generate snapshots for the HTML snippets on my server. As soon as some request for the snapshot, I am executing new Pageres(...).src(..).dest(..).run(..) and it does generate screenshot and saves it. However the chrome instance still remain in my processes which is eating up complete memory and cpu eventually. Is there any handling which we can do to control this behaviour ? It was also creating some defunct(zombies) process as well which I am killing in an interval using a NodeJS script already, but I can't kill these because they might be doing something at that moment of time.

Also the process doesn't respond if any page contains alert in it.
