[Bug?]: "Possible EventEmitter memory leak detected" when installing repository

[wojtekmaj]

Self-service

• I'd be willing to implement a fix

Describe the bug

Upon installing a repo (previously managed using Yarn 3) with Yarn 4, I got hit with these warnings:

➤ YN0000: · Yarn 4.0.0
➤ YN0000: ┌ Resolution step
➤ YN0000: │ MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 close listeners added to [TLSSocket]. Use emitter.setMaxListeners() to increase limit
➤ YN0000: │ MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 close listeners added to [TLSSocket]. Use emitter.setMaxListeners() to increase limit
➤ YN0000: │ MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 close listeners added to [TLSSocket]. Use emitter.setMaxListeners() to increase limit
(and it goes on for 100s of lines)

To reproduce

I can't reliably reproduce that. I was under poor network conditions at a time, though, so maybe it's related?

Environment

System:
    OS: macOS 14.0
    CPU: (8) arm64 Apple M2
  Binaries:

every time I run a clear install, this warning happens

Unfortunately without a reproduction it'll be very difficult to fix 🙁

Seems this might be a Node.js bug: nodejs/node#50136 soon to be fixed in the future 20.10 release

Hi! 👋

It seems like this issue as been marked as probably resolved, or missing important information blocking its progression. As a result, it'll be closed in a few days unless a maintainer explicitly vouches for it.
