After running the feed, the 'InitializationStatus' of the feed was persistented in Feed meta data (through JCR), but when deleting a feed, this meta data is not deleted. So
1. There will be garbage data left in the meta data repository
2. If the new created feed happens to have the same feed ID as the deleted feed, the new feed will get the wrong 'InitializationStatus'. Though this rarely happens, we did see this error in our test enviornment.
