Comment 2 for bug 1370730

The issue can happen if fmap notification for deletion of virtual network comes to schema transformer and schema transformer doesn't have any information about that network. There could be many reasons for why it didn't have information, but most common is, if you create and delete the network immediately, it is possible that the network is already deleted in cassandra by the time ifmap notifies schema transformer about its creation.

There is no impact of this bug since schema transformer will be restarted by supervisord.
