When BIG-IP negotiates settings over HTTP/2 connection, it adopts a value of peer's SETTINGS_MAX_FRAME_SIZE parameter as its own.
BIG-IP may accept a DATA frame with size above 16,384 bytes violating RFC.
A virtual is configured with HTTP/2 profile.
There is no workaround at this time.
BIG-IP no longer accepts DATA frames with sizes exceeding a default value of 16,384 bytes.
