Increased memory usage in nodejs version 20.16.0 due to fetch()

^{Originally posted by SteffenHo August 7, 2024} We saw a massive increase in memory in our next.js application after updating to version 20.16.0. We build our application with docker and the 20-alpine image. Other users were also able to confirm this problem: https://www.reddit.com/r/node/comments/1ejzn64/sudden_inexplicable_memory_leak_on_new_builds/

We then switched to version 20.15.1 and the memory returned to normal.

Maybe someone else could confirm this problem too?

@ronag could you have a look into this?
