Intermittently, HTTP2 experiences protocol resets.
Unexpected loss of HTTP2 frames due to protocol resets.
-- xfrag is 2 bytes in length. -- The header length is greater than 128. -- xfrag starts. For example, the following returns the incorrect header length: (0xFF BYTE1) next byte, http2_arbint_read.
No effective workaround.
HTTP2 now parses the request, regardless of its xfrags distribution.
