HLS problems - no play or repeat the same audio

Hi, I cant get this solve.

The problem is this: my http live streaming (HLS) work sometime and then stop or plays an old audio for some seconds

I have a flash media encoder (FME) and a Flash media server 4.5 (FMS).

I am encoding only audio from my FME to FMS, AAC 64k

I have a radio player in my web that works with jwplayer 6 and rtmp. That works great. no problem at all.

The problem is the HLS with iOS

Here its my configuratio:

Server:

/fms/applications/livepkgr/events/myevent/live

<Event>

  <EventID>live</EventID>

  <Recording>

    <FragmentDuration>4000</FragmentDuration>

    <SegmentDuration>400000</SegmentDuration>

    <DiskManagementDuration>1</DiskManagementDuration>

  </Recording>

</Event>

FME:

FME stream conf:

rtmp://myip/livepkgr/myevent

stream: livestream?adbe-live-event=live&adbe-record-mode=record

I try with  ;adbe-record-mode=record and without that

here is the content of the stream folder:

When the HLS stop working or simple repeat old stuff, I delete all this files and start encoding again.

I really dont know what else I can do.

Any idea or suggestion?

Really Thanks
