delete mass photo upload task?

Hello everybody,

I have tried to use the mass photo upload iview in the portal (com.sap.netweaver.coll.demo.UserPhotoAdministrationMassUpload) to upload some photos. Unfortunately I entered an invalid path for the parameter "upload folder". This resulted in a photo upload task that is still running. I have tried to restart the portal, but the task stays active. Does anyone know how to delete this task?

Best regards,

Ardiles
