CFC中的通信故障链接与查询

Question

我有一个CFC,可以在工作发布网站上处理"与我们联系"的表格.cfc旨在处理网站上的几种不同形式; 一个通用的"联系我们"表格和另一个"我对这份工作感兴趣"表格.

当CFC获取数据,并且作业发布的ID#在参数中时,CFC执行快速查询并获取作业发布信息,将其包含在电子邮件中并向HR部门和用户发送电子邮件职位发布信息以及用户的联系信息.

如果未检测到ID,则CFC仅通过电子邮件向用户发送确认电子邮件,并将联系信息发送给HR部门.

处理通用(非ID)表单时,一切正常.但是,当需要处理包含快速查询的表单时,我收到一个错误:

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.

为什么填充我的页面的查询工作正常,但是这个CFC会在其中引发查询错误？

我们在共享托管环境中运行带有MYSQL的CF9.

我不认为这是您的代码的问题,而是您的托管公司应该考虑的问题.

可能发生的事情是ColdFusion正在尝试从其连接池重用数据库连接,但通信链接已损坏.您通常可以通过向数据源设置(例如SELECT 1)添加验证查询或禁用连接池来解决此问题.
