Clearing and restarting the Print & Task Queue

By regularly removing unneeded tasks from the Print & Task Queue, you can keep critical tasks (like emails, payroll, backups) running reliably.

For example, if some tasks have had the Waiting status for more than a week, then you should delete them from the queue.

To keep the user interface uncluttered, you can also use a system script to easily remove all tasks that either completed or failed with an error.

Before getting started

You need to be a queue administrator, with the Is queue administrator checkbox selected on your User Preferences form (File > Preferences).
You need to have access to the Processing System Status and Setup form.

Go to System > Utilities > Processing System Status and Setup.
Filter the jobs:
- Select All queued jobs.
- Set Status to All.
- Set the After date to as early a date as possible, like 01/01/2000, to show all jobs.
Check the Status column for jobs you might want to delete, e.g. jobs stuck on the Waiting or Held statuses.
Select Server processor status.
Click Stop all processors. This lets you delete items any job.
Go back to All queued jobs, then right-click on a job (or multiple jobs) and choose Delete.

Go to Process > Task Scheduler.
Choose the Clear print and task queues task.
Select if you want to run the task once or schedule it to run regularly (e.g. once a week on weekends, when there's not much activity in Greentree).
Select the Run now checkbox.
Select all the Purge checkboxes, but do not select the Compact Database file checkbox.
Click Add to task queue.
