Basically what's happening is the app fires off a new noise floor request every 5 seconds, but it doesn't check if the last one is still running. So sometimes two requests end up overlapping. When the older one eventually times out, it goes "oh something's wrong" and shuts down the whole polling loop, even though everything was actually working fine.
