Airtime Liquidsoap and Webstream Problem

Most time my Airtime will go silent based on the the webstream reporting an "incorrect type" in the liquidsoap log
I set up the 24/7 playlist for  failover but when the streams failed ,Airtime go silent instead of moving to the playlist.
Could you tell me if something like the make failsafe,I read in the liquidsoap manual could resolve this issue?

Also why this Url  http://radio100.zapto.org:8000/  gives a "No MIME type found for webstream?" it plays im Amarok,Vlc and all other players

I checked all my dependencies and they all seem okay.I notice that my liquidsoap stop on some web-stream and it will not comeback until i issue a [sudo service airtime-liquidsoap restart ]command followed by crtl-c
as per

sudo service airtime-liquidsoap restart
Restarting Liquidsoap: ^CTraceback (most recent call last):
  File "/usr/lib/airtime/pypo/bin/liquidsoap_scripts/liquidsoap_prepare_terminate.py", line 14, in <module>
    tn.read_all()
  File "/usr/lib/python2.7/telnetlib.py", line 325, in read_all
    self.fill_rawq()
  File "/usr/lib/python2.7/telnetlib.py", line 516, in fill_rawq
    buf = self.sock.recv(50)
KeyboardInterrupt
Done.

the playout  is okay with the correct metadata which shows that airtime and apache is ok
the other mount points work okay. so Icecast is okay
