CFC中的通信故障鏈接與查詢

Question

我有一個CFC，它在工作發佈網站上處理「聯繫我們」類型的表單。 cfc旨在處理來自網站的幾種不同形式;一個通用的'聯繫我們'表格和另一個'我對這份工作感興趣'的表格。

當CFC獲取數據，並且工作發佈的ID＃在參數中時，CFC將執行快速查詢並抓取工作發佈信息，將其包含在電子郵件中併發送給HR部門和用戶包含工作發佈信息的電子郵件以及用戶的聯繫信息。

如果未檢測到ID，CFC只會向用戶發送確認電子郵件並將聯繫信息發送給HR部門。

處理通用（非ID）表單時，所有表現都很好。但是，當談到時間來處理，其中包括快速查詢我得到一個錯誤的形式：

Communications link failure The last packet successfully received from the server was 61,380 milliseconds ago. The last packet sent successfully to the server was 0 milliseconds ago.

爲什麼是填充我的頁面做工精細，但這CFC拋出一個錯誤，在其查詢查詢？

我們在共享主機環境下運行帶有MYSQL的CF9。

我不認爲這是你的代碼有問題，而是一個託管公司應當尋找到。

可能發生的事情是ColdFusion試圖從其連接池中重用數據庫連接，但通信鏈接已斷開。您通常可以通過向數據源設置添加驗證查詢（例如SELECT 1）或禁用連接池來彌補這一點。

我不得不歸功於史蒂芬ERAT就這一特定問題的知識：http://forums.adobe.com/message/3396333#3396333
