時々ハングしているように見える.Net 4.0 WPFアプリケーションがあります（1日に1〜2回）。アプリケーションはすべて、ユーザー アクティビティの監視に関係しているため、多くのネイティブ コール (EnumWindows、GetForegroundWindow、GetLastInputInfo など) を使用します。また、このアプリケーションは、SQL Server CE 4.0 データベースを使用して情報の一部を保存します。
これらのハングの 4 ～ 5 件からクラッシュ ダンプを取得することができました。それらはすべて非常によく似ていますが、問題の原因を突き止めるのにまだ苦労しています。
以下に、最新のクラッシュ ダンプの DebugDiag 分析の結果を示します。これの約 20 秒前に取得されたクラッシュ ダンプは、まったく同じ結果を示しました。このことから、他のスレッドを待機させている 2 つのスレッドがあるように見えます。
17 - このスレッドは、CE データベースにデータを挿入しています。このスレッドがハングする理由がわかりません。
22 - スタックトレースから、このスレッドが何をしているのかわかりません。
アプリケーションは、いくつかの場所で System.Threading.Tasks を大量に使用してタスクを開始し、さまざまなイベントを処理するため、非常に多くのスレッドが存在する可能性があります。一部の読み取りでは、Thread 22 は LoaderLock の問題のように見えますが、私は DllImport を介して標準の Windows API 呼び出しを使用しており、カスタム C++ コードはありません (通常、この問題が発生するようです)。
現時点で私は少し立ち往生しているので、アドバイスや指針をいただければ幸いです。
大きすぎるため、完全な DebugDiag 結果を投稿することはできませんが、最も重要と思われる部分を以下に示します。
