Recently I started having problems - suddenly turned off "On air" button. In Airtime playback continues, but Icecast status - "Airtime offline". The command "sudo service airtime-playout restart" solves the problem, but after a while the problem persists (problem repeated).
After restarting the Ubuntu server, a long time everything is in order, but then again off the air.
In pypo log I found the following lines :
ERROR - [pypofile.py : copy_file() : line 43] - Could not get size of source file: /srv/airtime/stor/imported/2/unknown/unknown/unknown_track_name-320kbps.mp3
And
WARNING - [pypoliquidsoap.py : handle_file_type() : line 69] - File /var/tmp/airtime/pypo/cache/scheduler/292.mp3 did not become ready in less than 5 seconds. Skipping...
