[huseeiin]

Version: Deno 2.4.2

Reproduction

deno run -A npm:create-solid@latest
select SolidStart, Yes for TypeScript and basic for the template
then install dependencies, build with deno-server preset:

import { defineConfig } from "@solidjs/start/config";

export default defineConfig({ server: { preset: "deno-server" } });

after running the server with deno task --config .output/deno.json start, run this code:

for (let index = 0; index < 10_000_000; index++) {
  const a = new AbortController();
  await fetch("http://localhost:3000", { signal: a.signal });
  a.abort();
}

you'll see the server crash with the error.

i think this doesn't happen anymore but the performance got degraded, its now slower than node. any confirms @bartlomieju?

Can you be more specific? What exactly has degraded? Do you have a benchmark you can share?

Happened to me, with using fetch, and doing few parallel requests.

error: Uncaught (in promise) "resource closed"

I hit Cmd+R 5 times in my browser, saw console.logs from first three requests, and then process quit completely, with this error message.

Before that, when I was refreshing (making 1 request at a time), it was handling 10s of requests no issues.
