You can cancel scheduled maintenance of a collection if it is no longer needed.
To cancel scheduled maintenance, perform the following steps.
From the Collection drop-down list, select the collection for which you want to remove maintenance.
Select the task you want to for which you want to remove scheduled maintenance: Reindex or Update. If a task is scheduled the details are now displayed.
For an Update task, check the Delete checkbox next to the task you want to remove.
UNIX/Linux users must restart the cron control process after removing scheduled maintenance, in order for their changes to take effect.
