明らかにロックの問題が発生していますが、それを読み取る方法がわかりません。たとえば、「- locked」を含む最初の行は「a java.util.ArrayList」と言っています... これは、ResponseStream.getPacket() (466 行目) でsynchronized、サブジェクトを持つ ArrayList を使用してブロックを実行していることを意味しますか? ?

現在、アプリ全体がロックされており、このようなスタック トレースが他にもたくさんあります。問題が発生している場所を確認できるように、これを読み取る方法を見つけようとしています。

アップデート

これは、データベース接続プーリングに C3P0 を使用する Web アプリケーションです。次のスレッドからわかるように、データベースのロックが発生しています。これをデバッグする他の方法は知っていますが、私の本当の質問は、単にこれらのスレッド ダンプをどのように読むべきかということです。

JDBC 呼び出しでのこの種のロックは正常です。あなたの問題は JDBC レイヤーにあるのではないかと思います。

データベース コンソールが表示されないため、問題はデータベース側のデッドロックまたはクエリの停止のいずれかであると推測されます。もう一度データベース コンソールを確認してください。問題は JDBC コードにあるようには見えません。データベース コンソールが表示されない場合は、JDBC で SQL トレースをオンにして、実行中のクエリを確認してください。

真の Java レベルのデッドロックは、スレッド ダンプに明確に示されます。データベース クエリの応答が非常に遅く、すべての接続が使い果たされているというパフォーマンス上の問題があるようです。

同じ問題が発生しました。c3p0 が hibernate で awaitAvailable でハングするのを参照してください

c3p0 デバッグ モデルを使用して、コードのどの部分がセッションを使用し、解放しないかを調べます。

c3p0 構成を追加します。

debugUnreturnedConnectionStackTraces = true;  
unreturnedConnectionTimeout = 20 ; // That's i used for
