Hello Stefan, Hello Yann, me the http2 bug tester is calling again ;-)
We've the problem "most probably" since apadhe 2.4.29 that http2 stucks from time to time. While running two bash curl while loops the one using http1.1 always finishes in < 0.05s while the http2 one takes sometimes 0.4 to 20s to finish. Sadly i can't reproduce this all the time - mostly more requests more failures. As this is a production server i've no idea how to debug as the http2 trace logs might flood the harddisk. Thanks! Greets, Stefan
