Random hangs on specific requests until nginx is restarted

We have lots of video files with various range requests made by the video processors.
On some requests (usually with Range: bytes=-16), the server spits out the http headers then hangs until it timeouts, while the backend has no problem serving the same request.
When it happens, it always happens on the same URL.
Restarting nginx solves the problem for the affected URL.
I don't think the same URLs are affected again, I think it randomly affects different URLs each time.

@David111 I've had the same issue, any fix available to that !!

[genx86]

possible infinite loop in

lua-resty-http\lib\resty\http.lua line 189
-- chunked
while true do
local chunk_header = sock:receiveuntil("\r\n")
local data, err, partial = chunk_header()
if not err then
if data == "0" then
return body -- end of chunk
else
local length = tonumber(data, 16)

                local ok, err = read_body_data(sock,length, nreqt.fetch_size, callback)
                if err then
                    return nil,err
                end
            end
        end
    end

i think it causes the problem, i added else in the loop to exit, and it didnt hang again (not sure if that was the issue)
