Currently i have multiple sites where sometimes tasks stagnate. Often this is the ‘Remove Old Page Versions’- and ‘Reindex Content’ Task. I receive a cron message with the message “PHP Fatal error: Allowed memory size exhausted”.
Furthermore i have some custom tasks that work fine when i run them from the interface but as soon as the cron starts the tasks they stagnate. There is no clear cause.
I did see some messages about the EntityManager being closed but no DB errors that could explain that.
Are more of you experiencing issues with tasks?
