jdbc - c3p0 jdbc デッドロックの問題

Question

私のアプリケーションは tomcat+spring+hibernate+mysql に基づいています。tomcat のバージョンは 7.0.25、spring は 2.5、hibernate 3.0、mysql 5.1.53 です。接続プールは c3p0-0.9.1.2.jar、jdbc ドライバーは mysql-connector-java-commercial-5.1.14-bin.jar です。特にテーブルが大きくなると、アプリケーションで多くのデッドロックが発生しました。ここでは、jprofiler による 1 つのデッドロックのスタックをダンプします。

tomcat server.xml の C3P0 構成は次のとおりです。

  <Resource type="com.mchange.v2.c3p0.ComboPooledDataSource" 
    jdbcUrl="jdbc:mysql://localhost/itms?max_sp_recursion_depth=10"

    minPoolSize="15" 
    numHelperThreads="10" 
    unreturnedConnectionTimeout="900" 
    user="root"
    password="admin" />

私の設定は間違っていますか？助けてください
