            This is the reason:

            2018-10-19 13:01:24,650 [14] DEBUG Couchbase.Core.VBucket - System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.
            at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
            at Couchbase.Core.VBucket.LocatePrimary()

            The VBucket map seems to somehow be impacted by the patch.
