If using the Health Check Application and the 'Start Appian Health Check' action, the following error will be seen:

Cause

When the Health Check runs, it creates a file in the system called health-check-status.json. If the Health Check is abruptly cancelled before it completes, the health-check-status.json file will continue to have the status as 'RUNNING'. The user will be unable to initiate a new Health Check because the system believes there is already one running. 

Action

1. Navigate to /design and click on the Objects tab.
2. In the search bar, search for the document called "health-check-status". Click on the file and it will open /designer.
3. Click on health-check-status.json. The file will download to your computer.
4. Open the file in an editor and if it indicates the status as 'RUNNING', delete the health-check-status.json file from /designer.
5. Initiate a new Health Check.
