Description
Title: what is the behavior when https stream identifiers are exhausted.
Description: In a setup with an upstream where h2 is set, but no max_stream_duration or max_requests_per_connection is set towards an upstream.
Is it possible to run into a problem where HTTP2 connections where the stream id is exhausted (more than 2^31). What is the behavior of envoy as a client in the scenario?
Also the same question applies to downstream, does envoy implement the GOAWAY to handle these situations?
A related RFC chapter mentions this:
Stream identifiers cannot be reused. Long-lived connections can result in an endpoint exhausting the available range of stream identifiers. A client that is unable to establish a new stream identifier can establish a new connection for new streams. A server that is unable to establish a new stream identifier can send a GOAWAY frame so that the client is forced to open a new connection for new streams.
