HLS stops and no file under applications/livepkgr/streams/_definst_/mystreamname

Hi, I set up an audio only stream with FME to my FMS 4.5

This are the FME parameters:

envivo?adbe-live-event=envivo&adbe-audio-stream-name=envivo&adbe-audio-stream-src=envivo

FME conf xml

<?xml version="1.0" encoding="UTF-16"?>

          <filler>

                          <duration>50</duration>

                          <buffersize>6000</buffersize>

          </filler>

  <logs>

                           <enable>true</enable>

I am using iphone and jwplayer 6 in myiphone.

The streams run perfect and sundenly it stops and in the folder applications/livepkgr/streams/_definst_/envivo I have no files.

Then, if I stop and start the FME it starts again with no problem.

any idea?

Now I turn on my log in the FME.

thanks
