Wowza HLS Timeout

Hi I have a videoplayer app requesting HLS streams from a wowza server. the issue i'm encountering is that the videoplayer buffers a certain amount of chunks during the stream and stops requesting for any more additional chunks for a prolong period of time. This is bad because it needs to keep requesting from wowza in order to keep the streaming session active.

So what happens is after the stream closes roku videoplayer plays the remaining chunks it has then kills the player. Has anyone encountered an issue like this before ?
