Having trouble with the Indexing service not being able to start properly at times. I seems like the ObjectStore types are not able to register because it's schemas hasn't been properly initialized.
This is normally solved through a restart of the service, but it keeps happening now and again which makes the Indexing unreliable. Has anyone had any similar problems or have any ideas of what could cause this issue?

Error message from the indexing service:
ERROR [7] EPiServer.IndexingService.ConfigurationHandler.RegisterTypes - Failed to register types. Will try later.
EPiServer.BaseLibrary.RepositoryException: Schema DefaultItem not registered.
