@julien-f Ahh.. perfect!
This a huge help until the other matter can be dealt with. I see it now and the testing is successful with this change.
Thank you again to you and the team!
You do need a lot of virtual memory for build but you can get by with 2GB ram + 4 GB swap if you tell nodejs to limit it self, by setting
export NODE_OPTIONS='--max-old-space-size=3072'
before starting the build process
