Issues with recorded videos

I am handling an application that records live videos from the browser to Wowza. Everything works fine except sometimes the videos recorded are of 119bytes only, i.e there is nothing. Out of 100 videos we record per day, atleast 5-6 of them always have this problem. The problem is very intermittent. Is there a way in wowza to notify or log that videos are not getting recorded or it is losing the stream, Which event is that, Why this problem should occur?

below is an example from the stats log
