Chrome Version       : Google Chrome 69.0.3497.100
URLs (if applicable) :
Other browsers tested: No

What steps will reproduce the problem?
(1) install Node and Light House module on Redhat linux machine
(2) write a NodeJS script to execute 6 different urls of Retail vedors like amazon.com, target.com, kohls.com for 3 times and take the median value
(3) script should launch headless chrome for these 6 urls and capture the parameters like speed index, time to interactive, First Content Load etc
(4) store these values in to Elastic Search DB using Http Node Module

What is the expected result?
- script should execute successfully.

What happens instead?
- i have this script configured using crontab to run daily once. it ran successfully for couple of days. however, it started failing now. script seems to be shutting down after executing few urls. co-incidence issue i was reported was that, Memory full with /tmp folder notification reported. all i can see in tmp folder is some "lighthouse.xxxxx" folders created. i think these for GPU related. not sure what is causing the script to halt before completing the execution.
