    Periodically Airtime will go "Off Air" while show content is programmed and running

    What would be the most elegant way to automatically restart icecast?

    Pseudo code:

    Do while

    Airtime = "on air" & Program Schedule = "active"

           If Airtime = "off air"
                 restart icecast
                 eMail Alert Someone
           End If

    Next

    Thanks!

    Bob, I would want to try and debug and find out why it is off air.... is liquidsoap not transmitting, or is icecast crashing?

    We have been running 1.9.4 on ubuntu 10.04 LTS since december in production, and never had a crash yet :) 

    the log files should show some errors to help resolve the issue.

    Would be interested in seeing what is causing this.

    Stephen

    @Bob,

    I agree with Stephen, if true, this is a serious issue that should be addressed properly.

    Are you sure icecast is the culprit? I would be really interested in hearing more about this problem.

    We are running the latest DEV version because we were having HUGE issues with our NAS borking the database when it didn't mount in the proper sequence

    That seems to all be fixed but the off air thing popped up

    I'll pull and review the logs

    Thanks

    Did you check if there was something playing when the ON AIR light was
    off? It could just be a problem with the light, not the playout.

    I poked around the logs a bit

    Here's something that might be a clue

    From icecast/icecast.log

    [2012-05-17  14:52:51] INFO admin/admin_handle_request Received admin command metadata on mount "/airtime_128"
    [2012-05-17  14:52:51] INFO util/util_conv_string converting metadata from UTF-8 to ISO8859-1
    [2012-05-17  14:52:51] INFO admin/command_metadata Metadata on mountpoint /airtime_128 changed to "Airtime - offline"

    From apache error.log

    [Thu May 17 10:53:18 2012] [error] [client 127.0.0.1] PHP Notice:  Undefined offset: 2 in /usr/share/airtime/application/models/Schedule.php on line 368, referer: http://localhost/Schedule

    From the icecast2 logs

    Thanks!

    I think the section in apache error log is the source of this problem. I looked through the code and found what could be causing this error. 

    Will be fixed today, thanks!

    Hi,

    I think I know the cause of this problem. Quick question, have you been playing around with fade-in and fade-out? This will help me narrow down the problem.
