I am working on using Wowza logs to determine the amount of video watched on our web-server over a given period of time. In order to accomplish this, I am parsing the logs for play and stop events that have the same c-client-ID. The problem i'm running into is that I am, at times, seeing multiple play events / stop events with a duplicated or re-used c-client-ID value.

I correct in reasoning that for any connection to the server, the ID for that connection should be associated with a single play event and a single stop event. Is there any reason this c-client-ID value would be duplicated as described above?
