IT Process Automation

hi there, i've several tasks stuck in users queue, tasks are not finishing even after performing. any way to abort the tasks, processes for such tasks already aborted.

I have a similar problem here. Completed processes are staying in the tasks list ("my tasks" and "tasks").

I solved it via newstart of the orchestrator.

Is there any other (less severe) Resolution?

please elaborate the New start of Orchestrator?

Tasks remain in the Task view for 2 minutes after they are completed and then they are removed from the Task view.  

There is no general cause or solution to Tasks getting stuck.  If tasks are completed and remains in the Task view for more than 2 minutes, or the instance behind the Task is completed but the Task remains in the Task view the support team could be engaged to more closely review and assist.
