Database Error
  • Hello,

    Have been running airtime on Ubuntu Lucid for sometime.   But Airtime stopped playing out and zendphp.log is filled with these errors:

    which explains why there is no playout.

    Any ideas?

    try to restart monit :

    service monit restart

    and after this

    airtime-check-system
  • Tried that and it said:

    Stopping daemon monitor: monit.
    Starting daemon monitor: empty config, please edit /etc/monit/monitrc.

    Not sure how it could become empty suddenly..

    try this :

    dpkg-reconfigure airtime

    and press enter every time without change nothing...
  • I restarted airtime-playout and away it went.  But I wonder what happened?

    look at yours logs...

    /var/log/airtime
  • I'm having the same problem running 2.3.1-1 installed via synaptic package manager

    The only thing that fixes the issue is to do a reinstall over the existing and all starts working again

    Any suggestions?

    thanks
  • We are still having this issue...

    Anyone have any suggestions?

    Thanks

    open a console
    do an :

    sudo apt-get --purge remove airtime

    this command remove completely airtime

    and after this do an :

    sudo apt-get install airtime

    if you have errors, posts them here

    a stupid question ?

    Postgresql is installed on your machine ?
  • I think it's fixed

    The stream settings were set to use 127.0.0.1 instead of localhost

    I read in another thread that was a potential problem

    Been up for the past few days since the change with zero downtime

    Thanks
