Generating static HTML for pages - runs out of memory

[Bouncey]

Our repo is freecodecamp/guides

I have tried building our site on a platinum tier netlify account with 7GB of memory and the build fails in the same manner as below.

Travis-CI fails in the same manner also.

My machine also failed today after adding more content.

Am I doing something wrong or have we reached the limits of /packages/gatsby/src/utils/build-html.js

$ npm run build

> node seed && gatsby build


navData created

It took 229ms to create the nav data for 2395 pages

Node.js by default only allows for ~1.4 GB of memory to be used. To use more, run Gatsby like the following node --max_old_space_size=4096 ./node_modules/.bin/gatsby setting 4096 to as much memory as you need/have.
