Http client sometimes returns EPIPE when server does not read request body

• Version: v15.12.0
• Platform: Darwin Kernel Version 20.3.0

What steps will reproduce the bug?

let http = require("http");

let server = http.createServer(async function(req, res)
{
	res.end("ok");
});

(async function()
{
	await new Promise(resolve => server.listen(resolve));
	let buf = Buffer.alloc(50000000);
	for(let i = 0; ; i++)
	{
		let req = http.request({ port: server.address().port, method: "post" }).end(buf);
		let res = await new Promise((resolve, reject) => req.on("response", resolve).on("error", reject));
		let str = "";
		for await (let chunk of res) str += chunk;
		console.log(i, "client received:", str);
	}
}());

How often does it reproduce? Is there a required condition?

Sometimes. It can take a few thousands of iterations or more.

What is the expected behavior?

No EPIPE.

What do you see instead?

85784 client received: ok
node:internal/process/promises:245
          triggerUncaughtException(err, true /* fromPromise */);
          ^

Error: write EPIPE
    at WriteWrap.onWriteComplete [as oncomplete] (node:internal/stream_base_commons:94:16) {
  errno: -32,

  syscall: 'write'
}

Additional information

It does not happen on linux (after more than million iterations).

Commencez par exécuter sur Darwin la reproduction fournie du client/serveur HTTP et comparez son comportement avec Linux. La charge utile n’indique aucun fichier source ni test, suivez donc le chemin d’écriture du corps de la requête du client HTTP associé à EPIPE et identifiez un test de régression ciblé. Le travail est terminé lorsque la reproduction ne produit plus EPIPE alors que le serveur ne lit pas le corps de la requête.
