Suddenly can't duplicate playlists

    Hello, we've been running 2.3.1 for quite some time without any issues. We're live both on FM and streaming via a relay.

    I've been scheduling a specific weekly slot for several weeks now and have always created a new playlist by duplicating the previous week's, editing it, and then dropping it into the calendar. Starting today, this is no longer working. Airtime seems to pause a moment but eventually I get 0:00 length playlist with no title. I believe other people schedule in the same way so this could be problematic for us.

    No system updates had been done for a few months (running 12.04.2 LTS) so I am baffled as to what triggered this. Any suggestions as to where I should begin looking? I do notice some php errors in zendphp.log, which were not happening before:

    But again, what could have caused this?

    Hi Ed,
    what does "sudo airtime-check-system" say? everything running?
    Is it possible, that one of the files of the previous playlist got deleted?
    cheers

    Woah, big problem:

    AIRTIME_SERVER_RESPONDING      = FAILED


    This is odd. We haven't had a problem for months. I can't do a fresh install as this system is live. Any suggestions?

    Airtime was streaming without problems last night but we were on an off-air block (we share the frequent with 2 other groups so we're only on air ⅓ of the week). We come on today at 1pm EST. Do you think we'll fail to produce audio output?

    I updated packages not related to airtime last night but didn't touch those I worried might affect the install. The pending list:

    The following packages will be upgraded:
      apache2 apache2-mpm-itk apache2-utils apache2.2-bin apache2.2-common apport gpgv libapache2-mod-php5 libapt-inst1.4 libasound2 libc-bin libc-dev-bin libc6 libc6-dev libdrm-intel1 libdrm-nouveau1a

    One last thing: the web status panel shows no issue. See attached image.

    did you reboot the machine since updating packages?
    You say you are only 1/3 a week on air, so reboot the server during off-air-slot.

    I did.

    I tried duplicating a playlist yesterday evening and noticed the problem. I ssh'd in, couldn't find anything wrong, and noticed updates pending. We were off the air so I applied them, then rebooted the system. I confirmed we were still streaming afterward.

    This is where I am now.

    Ok, I just noticed something else: several of the recent playlists now show a length of "N/A". Each was a copy of the previous one and I know these were valid because they were scheduled and played. 

    At one point (perhaps the one date 20130621) I built the playlist using dynamic blocks to randomly fill PSAs and Bumpers, and I'm guessing this is why that playlist shows the leading "~". Still, I don't understand why this would keep working until now.

    I just worked around it by copying 20130613 to create today's playlist. I'm still hoping we're going to air at 1pm EST though.

    I'm attaching another screenshot showing what a copy of 20130802 results in. There's no menu so I can't even edit the name or content. I have to log in as admin to delete this playlist.

    BTW, I'm subscribed to notifications when comments are made but I'm not receiving them and I seem to be missing the popups. I'm also not sure where to view / edit my email to confirm it's correct. Is this possible?

    Thank you for the help, hoerich.

    1pm EST: we're broadcasting. 

    Any idea why the status script reports an error?

    hm, try
    sudo service airtime-playout restart

    logs would be nice.
    sudo airtime-log --dump

    Is it safe to do this while broadcasting? We'll have a break between 16h-20h EST so I can try it then if it might interrupt playback.

    Ok, I ran the command and I'm still getting the error:

    AIRTIME_SERVER_RESPONDING      = FAILED

    The logs are here:


    (Hope there's no sensitive info in there).

    Some other notes: we're running airtime on port 1000, if that makes a difference.
