1. Ensure that the "Catch All" server subnet that is set by default is deleted as this will usually bring in too many servers.
2. On each Collector/MTP set the "force positive config" setting as documented in the link below to ensure that ADA only created User Modified Applications, this will prevent System Defined Applications from being created and causing the database issue.

3. If there are too many server and applications in the system already, you may have to uninstall ADA and reinstall ADA with a fresh database.
**Note**
You may want to export your list of servers and make note of your user defined Application Definitions before uninstalling.
If you have setup HTTPS you may want to back up the files and directories listed in HTTPS setup instructions below:

4. When uninstalling follow the steps in https://knowledge.broadcom.com/external/article?articleId=75046
