Problems

HEAP memory. The V8 engine has run out of memory (JavaScript heap), and it is unable to allocate more memory to the application or script.


Removing the live editor, all pages except the main and component pages, and unnecessary plugins does not solve this problem. Changing the environment variable (NODE_OPTIONS=--max-old-space-size) to 8192 and 12288 still causes a memory limit error. Although on some devices (MacBook Pro, Apple M1 Pro chip, 16 GM memory) after a long assembly (3-5 minutes) it was possible to obtain an insignificant result, without functionality.
To test performance, I removed all components and returned one component at a time to the project. The first problems of a long assembly begin to appear when 20 components are returned. If we return all 75 components, we return to the problem of using a large amount of memory.

Possible reasons

A possible problem could be upgrading the versions of the @mdx-js/mdx, @mdx-js/react and gatsby-plugin-mdx packages.
