Running for two hours, looks promising.

Only see a few, (what is normal ?):
[h2:warn] [pid 1652:tid 2852] (70015)Could not find specified socket in poll
list.: [client 80.135.160.180:3313] AH02953: h2_mplx(108): stream for
response 47
[h2:error] [pid 7300:tid 3160] (OS 10054)An existing connection was forcibly
closed by the remote host.  : [client 27.7.220.245:50275] AH02925:

I think I found a possible race that could cause this. Please install the
latest version in 2.4.17-protocols-http2, when you find the time, and let me
know if you see any change.
