HTTP client seems to get stuck somewhere when error from transport layer is logged

[SeaRoll]

Bug description

We use the http client and whenever a connection is slow/lost for a short while, the error in the log says:

E (378225) transport_base: esp_tls_conn_read error, errno=No more processes
W (378225) HTTP_CLIENT: esp_transport_read returned:0 and errno:11

The current code looks like such:

fn get_cloud_device_data(
        &self,
    ) -> Result<CloudDeviceDataResponse> {
        let connection = EspHttpConnection::new(&Configuration {
            use_global_ca_store: true,
            crt_bundle_attach: Some(esp_idf_svc::sys::esp_crt_bundle_attach),
            timeout: Some(core::time::Duration::from_secs(30)),
            ..Default::default()
        })?;

        let mut client = Client::wrap(connection);

        let headers = [
            ("accept", "application/json"),
            ("cache-control", "no-cache"),
            ("content-type", "application/json"),
            ("content-length", &buf.len().to_string()),
        ];

        let mut request = client.request(Method::Post, DEVICE_DATA_ENDPOINT, &headers)?;
        request.write(&buf)?;

        log::info!("Submitting request");
        let response = request.submit()?;
        let status = response.status();

        log::info!("Received code: {}\n", status);

        match status {
            200 => {
                // Error seems to happen here somewhere
                let mut buf = [0_u8; 1024];
                let mut result = Vec::new();
                let mut reader = response;
                while let Ok(size) = Read::read(&mut reader, &mut buf) {
                    if size == 0 {
                        break;
                    }
                    result.extend_from_slice(&buf[..size]);
                }

                let result = serde_json::from_slice(&result)?;
                Ok(result)
            }
            _ => Err(anyhow::anyhow!("Unexpected response code: {}", status)),
        }
    }

• Would you like to work on a fix? [y/n] (not yet, need to investigate why)

To Reproduce

1. Have a bad internet connection (but still connected)
2. Call any HTTP endpoint (that has lots of buffered data 400KB+)
3. If the internet connection is bad enough, it gets stuck

Expected behavior

Some kind of error, but I am not sure if this is just me being bad at coding 🤔
