错误：子 pid 6695 退出信号分段错误 (11)

Question

我使用django + mod-wsgi + apache开发一个网站。奇怪的是，当我启动网站时，除了登录功能之外的所有其他功能都可以。当我尝试登录时，出现 500 错误。

这是错误形式 error_log：

请阅读文档了解常见原因：

http://code.google.com/p/ modwsgi/wiki/FrequentlyAskedQuestions#Apache_Process_Crashes
http://code.google.com/p/modwsgi/wiki/ApplicationIssues

尝试使用调试器来跟踪它：

很可能您的登录页面会导致导入和使用扩展模块，但该模块在子系统中不起作用口译员。尝试使用以下命令强制该应用程序在主解释器中运行：

WSGIApplicationGroup %{GLOBAL}
