这个错误是什么意思？ [二郎，受Mochiweb中，MySQL]

Question

我与Erlang和受Mochiweb彗星聊天服务器。我运行“./start-dev.sh”来启动服务器。但是，约1个月后，我得到了以下错误：

=ERROR REPORT==== 26-Sep-2009::09:21:06 ===

                 "closed"]}}}}

和如果打开的以下数字成字符

            [70,97,105,108,101,100,32,115,101,110,100,105,110,103,32,100,

             "closed"]}}}}

它们是

Failed sending data on socket :"closed"

这是否意味着我与MySQL连接或插座有问题？ 我不知道这个错误有事情做与我“./start-dev.sh”或者我只是有一些错误的设置？

和我有什么别的信息，以提供用于诊断？

感谢，并期待您的答复？

它看起来像某处环/ 2函数不处理的{错误，错误}从函数调用返回。这将导致其崩溃的过程中的误差。如果没有它的代码是很难说是什么原因造成的错误返回。
