Deployment directories and related files are left under each server instance's /tmp/vfs directory between deployments and re-starts. Over time, this can waste a considerable amount of space, expecially when many deployments occur.
The directories and files under a server instances /tmp/vfs directory should be deleted when the server instance is shutdown or as a server instance is being starting. This is true for deployments also. These files and directories should be removed between re-deployments.
