Event ID 132 — Task Scheduler Service Quotas

  • Article

Applies To: Windows Server 2008

The Task Scheduler service manages a queue of tasks that are scheduled to run. A task is put in the queue when the service determines the task should run. The Task Scheduler task queue has a quota that defines the number of tasks allowed in the queue. The quota is defined in a registry key value.
