Sorry, I forgot to mention, I pushed another patch that may help you.
In HAProxy 2.0, it is the commit 0bf28f856 ("BUG/MINOR: mux-h1: Close
server connection if input data remains in h1_detach()").
I don't know if your HAProxy already includes it or not. If not,
please give it a try. If your tests were made with this last commit,
it means there is a bug somewhere else.
Just tested with haproxy-ss-20190720 and I do not see any strange 502's
anymore. Thanks!

Ah, no, I used vanilla 2.0.2 with only your other patch applied. I see
if I can test again.

I just pathed up 2.0.2 and tested it. I still get 502's but a lot less.
I'm not sure if this is because I do less request/s or I hit something
else. The show errors show:

There is of course more with the first one, but I do not want to put
that on the mailinglist. It seems like a partial response body. I can
send it to you private if you want.
