Deployments are removed from the content repository as part of management operations that remove them from the configuration. But, if a server in a managed domain is stopped when those management operations occur, the content will not be removed from that server's repository.
Deployment content for deployment archives that are no longer used in the domain can accumulate in individual servers' content repository, wasting disk space.
EAP now periodically runs a background process that checks for and removes content in the repository that is not referenced in the configuration model.
If an archive has been removed from the domain while a server that has a copy of it is offline remains, the garbage collection protocol will remove it within 5 to 10 minutes of the server being started.
