The local store or direct replication of the Update could not be fulfill according to the given IWriteConsistency due to durable store errors. This is only used for entries that have been configured to be durable. The Update was still performed in memory locally and possibly replicated to some nodes, but it might not have been written to durable storage. It will eventually be disseminated to other replicas, unless the local replica crashes before it has been able to communicate with other replicas.
