web interface stucked
  • Hello,

    After some month of running airtime without big problems (one unexplained crash some weeks), now the web interface hangs when I try to add a new show.  Sometimes, my web explorer talk about the "mutation-summary.js:598" script who's stuck. I've try from linux and windows, with firefox or chromium, always the same problem.
    The logs doesn't show any errors :
    $ cat /var/log/airtime/pypo-liquidsoap/ls_script.log |grep warning
    $ cat /var/log/airtime/pypo-liquidsoap/ls_script.log |grep error
    $ cat /var/log/airtime/pypo/pypo.log |grep warning
    $ cat /var/log/airtime/pypo/pypo.log |grep error

    The server is up to date.

    It's possible the database was "corrupted" (due to hard reboot) without showing error in the posgres log ?

    Thanks for your help !

  • What about the PHP / webserver logs. The two places you were looking for errors are not directly related to where you might be having problems. I'm not 100% sure where the 2.5.1 logs are stored since I really started delving into the code post 2.5.2 but I believe it is stored in the zendphp.log there. That might have a more useful error as that is where any errors the web interface might provide are located.
  • Nothing in the apache log.
    About the zendphp.log :
    When I add a new show, my browser crash but I see nothing in the log. The new show is created when I reconnect.
    When I delete a show, just before stuck my bother, a line appear in the log :
    2016-01-27T15:28:26+01:00 INFO (6): [ScheduleController.php : eventFeedPreloadAction() : line 139] - month

    If I search for errors in this log, I find some occurrences like this :
    [index.php : () : line 73] - #0 /usr/share/airtime/application/forms/AddShowWhen.php(274): exception_error_handler(8, 'Undefined varia...', '/usr/share/airt...', 274, Array)

    It's help you to understand ???

  • On the interface code ? no. The only change I made is applying this script about recording sound without soundcard. I can disable it but I don't think is linked to my problem ?

  • I'm currently having the same problem right now.
  • Hello, I'm having the same problem. It stucks when I add a show, change metadata of a file, deleting a file, etc...
  • Which version of Airtime is everyone running ? I'm assuming 2.5.1 because that is the version that most people tend to run.

  • I have just had a similar issue today regarding adding a show to be recorded and rebroadcast. The error I had was similar to yours:

    2016-02-04T15:53:02+00:00 INFO (6): [index.php : () : line 71] - Undefined variable: hours
    2016-02-04T15:53:02+00:00 INFO (6): [index.php : () : line 73] - #0 /usr/share/airtime/application/forms/AddShowWhen.php(303): exception_error_handler(8, 'Undefined varia...', '/usr/share/airt...', 303, Array)

    I then compared the AddShowWhen.php file with the latest file on github:

    https://github.com/sourcefabric/airtime/blob/2.5.x/airtime_mvc/application/forms/AddShowWhen.php

    and noticed there were some differences, specifcally relating to this issue. So I just copied the github file to my server and it solved the issue. You might want to check/diff these files too as it may solve your problem.

  • Hello James Dunn,

    Thanks for your message. I changed the file as you did but my problem was not solved...

    Once i reinstalled it was ok but it's maybe a problem of full disk space. Do you know how many space should be free for airtime works fine ?
  • This is what my server has:




    rootfs 20G 2.3G 17G 13% /

    /dev/sda3 3.6T 1.3T 2.2T 37% /mnt/airtime



    I always have the audio directory on a separate hard drive. If you have a few gigabytes free for the OS you should be fine.

    James
