[bug] After NGINX reload, stream info disappears from the statistics page.

[DroidU]

If I reload NGINX, the "live streams" value on the statistics page becomes 0 and all streams disappear. Regardless, all streams continue to work.
If I then reconnect to the NGINX server using the source client, the corresponding stream will reappear on the statistics page.

After reloaded, the old Nginx worker processes will not accept new connections but keep serving the remaining active connections (both publishers and subscribers), so statistics you saw then was ONLY from the new Nginx worker processes.
This is not mechanism of this module but Nginx itself to process long-lived connections.
That's why if your client reconnected to Nginx, the corresponding stream appeared again. Because it closed the connection to the old worker process and the new worker process accepted it.
