カスタム voip アプリケーションを作成しました。ほとんどすべてがうまく機能します。しかし、アプリケーションが再起動されるたびに。

今回は着信トラフィックはありません。アプリケーション ログから確認しました。
数分後、アプリケーションはネットワーク変更通知を受け取り、サーバーへの再登録を開始します。バックグラウンド タスクがそれを保護し始めます。クラッシュ バックグラウンド タスクが終了する 1 分前。しかし、アプリケーションはとにかく実行されます - ログに表示されます!
何が原因である可能性がありますか？

PPS Today は、アプリケーションで I/O アクティビティ インストルメントを実行します。2 つのことを発見しました。1) アプリケーションは 10 秒ごとに再開し、100 ～ 200 ミリ秒中断してから再開します。2) iOS システム コールにソケット I/O があります。SIP シグナリング ソケットではありません。http://trac.pjsip.org/repos/ticket/1482に似ているように見えます
しかし、難しいのは、切断された tcp ソケットを見つけることです...
