IPX fails sometimes under high load

[capraruioan]

We just deployed in production a news website, so we have high traffic.. All generated images are cached so we don't hit ipx everytime

However, some images are failing with a 502 error sometimes

I did a test with this piece of come

for (var i = 0; i <= 200; i++) {
	ff(i)

}

function ff(i) {
	setTimeout(() => {
		var img = document.createElement('img');
		document.body.appendChild(img);
		img.src =  '/_ipx/f_webp&enlarge_true&fit_cover&s_680x420/link_to_image?qq=' + Date.now() + '-' + Math.random();
	}, i * 50)
}

On staging env where is low traffic we have 200/200 successful requests
On production we have about 10/200 failed images when requesting directly on the nuxt app and we have 10-20 failed when requesting through the cache layer

Anyone else encountered this?

Would you be able to provide reproduction in stackblitz where this issue occurs? :)

Would you be able to provide a reproduction? 🙏

More info

Why do I need to provide a reproduction?

Reproductions make it possible for us to triage and fix issues quickly with a relatively small team. It helps us discover the source of the problem, and also can reveal assumptions you or we might be making.

What will happen?

If you've provided a reproduction, we'll remove the label and try to reproduce the issue. If we can, we'll mark it as a bug and prioritise it based on its severity and how many people we think it might affect.

If needs reproduction labeled issues don't receive any substantial activity (e.g., new comments featuring a reproduction link), we'll close them. That's not because we don't care! At any point, feel free to comment with a reproduction and we'll reopen it.

How can I create a reproduction?

We have a template for starting with a minimal reproduction:

👉 https://stackblitz.com/github/nuxt/image/tree/main/example

A public GitHub repository is also perfect. 👌

Please ensure that the reproduction is as minimal as possible. See more details in our guide.

@Baroshem I am not able to provide a reproduction. As I said, this happens on high loads and I cannot simulate that on stackblitz

it happens also when accessing the image url directly as the example I've provided

this might be worth raising upstream on https://github.com/unjs/ipx.
