Hi,

Here's my config file:

set("log.file.path","/etc/liquidsoap/okradio.log")

url = "http://live7.okradio.net/listen.pls?sid=1"
input = mksafe(input.http(url,buffer=2.,max=120.))

output.icecast(
  %mp3(bitrate=64), 
  mount="/okradio.mp3",
  host="localhost", port=8000, password="xxxxxxxxxxxxx",
  input)

Any ideas?

Thanks

Johny

Found the solution!

Here's what it was in case someone runs into same issue. Icecast server had default limit of 2 how many sources can connect so it was so confusing, sometime it would work sometimes not because other .liq would connect and work but others would not. Changing 

<limits>
        <sources>22</sources>

inside /etc/icecast2/icecast.xml solved the issue. This error 2018/01/23 14:03:42 [stderr:3] strange error flushing buffer ... never came up again after above change Hope it helps!
