x/net/http2: conn_PROTOCOL_ERROR_reset_idle_stream #48658
Description
I have a Go HTTP/2 client & server load balancer front-end, talking to an HTTP/2 server backend.
6 days ago, running code from x/net HEAD at the time, I saw a few instances of the server backend's error counter conn_PROTOCOL_ERROR_reset_idle_stream.
That is, a Transport (also x/net/http2 at same rev) sent a RSTStream frame to the server for a stream that was "idle" as far as the server was concerned, so the server hung up on the client.
