Apache Dubbo Component

Dubbo Version

Dubbo 3.x

Steps to reproduce this issue

Based on the discussion in #13731, I think it is an improper way to make a reconnection triggered by GoAwayFrame(stream id exhausted) cause there will be 100% request failure before the new connection being active and it is unacceptable for production scenario. To make sure the connection is consistently available, is it possible to make a new connection before the stream id is about to be exhausted?

What you expected to happen

  1. Make a new connection before the stream id is about to be exhausted.
