Describe the problem

The undici dependency contains a code path that, starting with Node 20.16.0, results in memory leaks (in our experience significant). See nodejs/undici#3445 and nodejs/node#54274 for details about the issue.

Upgrading undici to v6.19.6 or later, will include the fix. As of yet the fix does not appear to be backported to v5 which this repository uses.

Steps and code to reproduce issue

See nodejs/undici#3445 for more details.

Hi @JesperLindholmNG, thanks for reporting this issue.

It seems that upgrading to undici 6.19.6 is non-trivial for us. Fortunately, we do plan to replace our usage of undici with native fetch in the coming months, which will resolve this issue- I'll update this issue with any updates as they come.
Edit: My bad, I didn't see #8432!

Hi @JesperLindholmNG,

I've updated our undici dependency to v6.19.7, which will be part of our next release. I'm going to close this issue for now. Please create a new issue if you encounter any problems with the new version. Thanks!
