I am having a problem too.
When running cron, it comes to this particular point:
Execute adhoc task: tool_dataprivacy\task\initiate_data_request_task
... started 08:55:14. Current memory use 35.6MB.
Generating the contexts containing personal data for the user...
Fetching data from 474 components (Wednesday, 21 November 2018, 8:55 AM)
Processing antivirus_clamav (1/474) (Wednesday, 21 November 2018, 8:55 AM)
Processing qbehaviour_adaptive_adapted_for_coderunner (233/474) (Wednesday, 21 November 2018, 8:55 AM)
After this point, the job just stops. There is no confirmation that the task completed successfully.
Can you please share some light on this.
Thans and Regards,
