aiohttp does not support concurrent requests exceeding 500.

[LeeYunhang]

Describe the bug

Concurrent requests over 500 will result in a "connect ECONNRESET" error, which seems to be random. I've noticed that the server uses the loop.create_server API, but locally, this API can support more than 10,000 concurrent requests. Could there be an issue with aiohttp's implementation?

To Reproduce

Create an aiohttp web service and use a script to simulate 1000 concurrent requests. The requests at the end might result in errors.

Expected behavior

No error

Logs/tracebacks

connect ECONNRESET
