Docs: Single item size exceeds maxSize

[adneforslund]

What is the documentation issue?

After upgrading to Next.js 15, the terminal as started to print "Single item size exceeds maxSize", but no place in the documentation is this mentioned. So my question is: What item is bigger than the maxSize?

Is there any context that might help us understand?

What item size exceeds maxSize?

Does the docs page already exist? Please link to it.

You might be customizing the cache handler with cacheMaxMemorySize: 0

I notice it too.

according to docs (https://nextjs.org/docs/app/building-your-application/deploying#configuring-caching)

cacheMaxMemorySize: 0, // disable default in-memory caching

Probably it's some warning, but it seems not intentioned, couldn't find this kind of message inside codebase.
