I have started website copying to an external directory via FTP at Plesk Panel (Centos 7). I wanted to stop it because it is too slow and will take it many days if I let it continue to run. I have tried
- Delete the running task from Plesk DB (from both longtaskparams and longtask)
- Restart Plesk via SSH
- service xinetd restart via SSH
All these did not stop the FTP Upload.
