In Centos 6.9 when I start service kaltura-batch it work only few seconds and it stop because I see in log that:
PHP Fatal error: Undefined class constant ‘COPY_CAPTIONS’ in /opt/kaltura/app/plugins/content/caption/base/batch/CopyCaptions/KAsyncCopyCaptions.class.php on line 35
And service monit sends many emails because service not work (monit alert – Does not exist batch)
