FOSFacebookBundleとFOSUserBundleとSymfony2を使用してユーザーを管理しています。ローカルですべてが正常に機能しました。ただし、すべてをステージング環境にプッシュすると、登録時にユーザーが（ドクトリンエンティティマネージャーを使用して）永続化されていないことに気付きました。
私が最初にチェックしたのは、エンティティマネージャーを使用して他のものを永続化できるかどうかでした。これはうまくいきました。次に、ログを確認して、挿入ステートメントが存在することを確認しました。
INSERT INTO user (username, username_canonical, email, email_canonical, enabled, salt, password, last_login, locked, expired, expires_at, confirmation_token, password_requested_at, roles, credentials_expired, credentials_expire_at, firstname, lastname, facebookID, date_of_birth, locale, gender, has_profile_pic, created_at, updated_at)
VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
({"1":"1234","2":"1234","3":"foo@gmail.com","4":"foo@gmail.com","5":true,"6":"","7":"","8":null,"9":0,"10":false,"11":null,"12":null,"13":null,"14":["ROLE_FACEBOOK"],"15":0,"16":null,"17":"Mr","18":"Foo","19":"1234","20":{"date":"1986-12-09 00:00:00","timezone_type":3,"timezone":"PRC"},"21":"nl_NL","22":"male","23":1,"24":{"date":"2012-07-06 01:34:47","timezone_type":3,"timezone":"PRC"},"25":{"date":"2012-07-06 01:34:47","timezone_type":3,"timezone":"PRC"}})
疑問符をプリペアドステートメントの値に置き換えて手動でクエリを発行すると、すべてが正常に機能します。
誰かがこれが何であるかについて何か手がかりを得ましたか？次にどこを見ればよいかわからないので、これをさらにデバッグする方法のヒントにも非常に満足しています。
前もって感謝します！
アップデート：
mysqlログをもう一度見てみると、INSERTステートメントが準備されているが、実行されていないことに気付きました（selectステートメントとは異なります）。エラーログにエラーが見つかりません。mysqlログは次のとおりです。

手がかりはありますか？
更新2：
PDOステートメントの実行のいくつかの戻り値をdoctrinelibに記録してきましたが、開発環境で通常の戻り値（1）を取得していることがわかりました。ただし、実稼働環境では戻り値が得られません。別のヒントのようですが、どうすればよいかわかりません。
ちなみにPDOStatement::errorCode00000を返します（すべてがうまくいったことを示します）
