I would strongly urge you to not spend a lot of time debugging HTTP/2 on that old release. We've fixed several HTTP/2 issues since then so you risk ending up chasing things or seeing symptoms that aren't present in the current code.
Can you write up a smallish example code that reproduces the problem? If I could point such a thing on my own test server I could take a look at it from my side. HTTP/2 debugging can be a bit complicated.
With app level logging I can see that CURLOPT_READFUNCTION callback gets invoked up until the point where another GET request happens, and then I see no callbacks anymore, and the connection eventually times out or is closed by the server.
This symptom matches a previous bug we had (and fixed) in curl's HTTP/2 code. -- / daniel.haxx.se ------------------------------------------------------------------- Unsubscribe: https://cool.haxx.se/list/listinfo/curl-library Etiquette: https://curl.haxx.se/mail/etiquette.html
