Using io uring after some seconds all the requests has 408 response

[lfdominguez]

Expected Behavior

Any request will be responded using the defined routes.

Current Behavior

All requests are responded with 408

Possible Solution

Knowing how io_uring works, maybe a pool waiting for a response on the queue of io_uring is blocking all the requests.

Steps to Reproduce (for bugs)

1. Start the app
2. Wait some seconds (30s)
3. Do any request to any endpoint
4. Get 408 response

Context

I'm using:

actix-web = { version = "4.11", features = ["experimental-io-uring"] }
actix-files = { version = "0.6", features = ["experimental-io-uring"] }

HttpServer::new(|| {
            App::new()
                // .wrap(TracingLogger::default())
                // .wrap(sentry_actix::Sentry::new())
                // .service(api::get_mpd_stream)
        })  // Disconnect timeout
        .bind(("127.0.0.1", 8080)).expect("Failed to bind server")
        .run()
        .await.map_err(|io_error| {
            CustomError::WebServerError(format!("IO Error: {}", io_error))
        })?;

Tried all kind of things, like disabling my only 1 service and all extra wrap, always get 408 response
