Dear support,

The Celery task scheduler does not seem to be running. This means that email sending and periodic tasks such as event reminders do not work.

then i check on the celery take , it’s running as below

Hint: Some lines were ellipsized, use -l to show in full.

and i try to restart the service, but the error message still that.

can you give me any advice on that?

thanks

Please post the full log (systemctl status -l indico-celery); the truncated lines are pretty much useless…
Also check /opt/indico/logs/celery.log.

If there’s no helpful info in the full log output, stop the service and (temporarily) run indico celery worker -B manually as the indico user and see if there’s any useful output there.
