Slow queries running in background after upgrade from OJS 3.2.1-5 to OJS 3.3.0-18

Hi @asmecher, I saw some background tasks after enabling the scheduled_tasks and Acron, but the metrics are not being updated(abstracts). It seems the same issue is reported here: The statistics of visits to the abstract are not recorded

Maybe the problem was that I set the scheduled_tasks off and am now back to On? How can I fix that?

I saw some scheduled tasks were on the Rejected page and moved them back to Scheduled, but it doesn’t work yet.
