Bug: Express errors when sending big file

[marvinhagemeister]

Steps to reproduce

1. Create a new directory and cd into it
2. Run npm init -y && npm i express && deno init
3. Create file server.mjs with these contents:

import express from "express";

const app = express();

app.get("/", (_req, res) => {
  res.sendFile("home.html", {
    root: import.meta.dirname,
  });
});

const port = 3000;
app.listen(port, () => {
  console.log(`Server listening on port ${port}`);
});

4. Create file home.html with the contents from here (too big to put as inline snippet) https://gist.github.com/marvinhagemeister/2b1cde3a3527637d12332550ab65eae4 . Alternative any other big (>3MB) html file should work
5. Run deno run -A server.mjs
6. Run wrk -d 10 --latency http://localhost:3000/

Hello, I tried reproducing it at the latest version and I didn't get the error.

I can still reproduce it with 1.44.4 or with git from today (2024-06-05)
