orionでngsiv2を使用するとcygnusがクラッシュするのはなぜですか？

Question

最近、私はNGSIV2で作業を開始しますが、cygnusはクラッシュを開始します。 私は正しく構成されていないことがありますか？ v1は完璧に動作します。エラーと

エラーは言った：エラーがチャネルにイベントを追加します。チャンネルが満杯になる可能性があります。チャネル容量を増やすか、シンクがより高速に実行されることを確認してください。

当面は、NGSIv2はCygnusではサポートされていません。それはexpected to be implementedですが、まだスケジュールされていません。

EDIT：あなたはオリオンで/更新エンティティを作成するためにNGSIv2を使用している場合NGSIv1で通知を持つことができることノートも：

• がNGSIv2を使用してサブスクリプションを作成しますNGSIv1操作
• を使用してサブスクリプションを作成します。 attrsFormatがlegacyに等しい操作です。より詳しい情報を見てくださいhere。
