    Also, in ls_script.log file the next strings apears every 10 seconds. Is that normal?

  • Do this

    liquidsoap --version

    If your version turns out to be

    Liquidsoap 1.1.1
    Copyright (c) 2003-2013 Savonet team

    There in lies your problem

    Solution you have to find the offending script that is causing this problem.

    In my case it is the tunein api ( I have since move mine from direct calls and in the coming weeks I will post a solution)

    Problem : if you have any script  (python,php or a mod ls_script) then this will occur

    Why it happen : it there is any script that is making a call to liquidsoap and its not connected at the time liquidsoap makes the request ,liquidsoap will try to catch that exception resulting in a built up of latency and if you scroll the logs you will also see "we must catch up ...seconds"

    Why not happen before:- the custom built and compile version of liquidsoap uses only the modules and plugins necessary hence it was more fault tolerant
    For some reason my liquidsoap is the repository version and this is not fully maintain so you ,might also want to compile and use the daily svn.

    Function Things which  also do not work and can cause problem
    perpend and smooth add.I will make a list as I go along

    Caution I hope nobody chose to excellently and miraculously decide the repo version.unless they do not like history

    Here is how I found the issues Tunein constantly go down nowadays and then I hear my back up file and search the log. One such incident was started at 0230 EST. 01302015.

    I have temporary suspend my sending to Tunein ,to find a fix (comment out the script) fixed 1335 on 01302015

    Good Luck

  • Here in lies a strategy

     "please be warned that the server is not meant to be used under heavy load. Therefore, it should not be exposed to your users/listeners if you expect many of them. In this case, you should use it as a backend/middle-end and have some kind of caching between harbor and the final user. In particular, the harbor server is not meant to server big files because it loads their entire content in memory before sending them. However, the harbor HTTP server is fully equipped to serve any kind of CGI script."

    http://savonet.sourceforge.net/doc-svn/harbor_http.html

    Which I hope to explore
