Sure, the config and debug level log of both working and
non-working connection are available at

Also worth noting is that if the client uses Connection: keep-alive
(instead of Connection: close), the problem does not appear, possibly
because the connection isn't closed right away.

It also only seems to appear if the response body is large enough.

I'll see if I can come up with some minimal setup to reliably
reproduce it.

Best regards,
