TitleLeaf processes long-running tasks in the background. Each background process is represented by a job in the TitleLeaf's Admin interface.
Jobs are processed by a job worker. Intermittently, the job worker may stop running. To test if it is running, click the Test Job Worker link in the sidebar.
If the worker is running, the message will appear in green. No action is required.
If the worker is not running, the message will appear in red. Click the Start link in the message to start the job worker.
