这个问题相当棘手，让我发疯。感谢您的帮助

我们有一些底层C代码，Python模块将调用这些代码（Python版本2.6，
Django
framework，版本1.4）。我们通过
SWIG
2.0.9构建了Python绑定。我们在
python manage.py shell
提示符中使用了它们。他们工作得很好

如果我们运行
python manage.py runserver 0.0.0.0:8001
，一切仍然正常。但是，当我们将应用程序部署为Apache虚拟主机时，Python绑定会突然失败（其他不使用C代码的网页也可以）。它的url类似于。这是我们的
conf
文件：

我猜这是由文件权限问题引起的。但是，即使我将所有Python绑定文件都设置为777，在作为Apache虚拟主机工作时仍然会失败

我确实尝试删除
dirver.close（）
语句，但仍然失败。在代码跟踪之后，永远不会调用
close（）
方法

可能有一些配置导致python绑定的生命周期没有得到正确管理。不过，我不能指出原因

请帮忙。非常感谢

阅读后，我将以下内容添加到我的

    这通常表示它仍在崩溃。试着使用gdb找出它崩溃的地方。看到了吗，但哪一个是有帮助的具体更改？@graham dumpleton在测试中，如果我删除
    LoadModule
    ，将报告
    脚本头过早结束。如果我删除
    WSGISocketPrefix
    ，它会报告
    权限被拒绝：无法连接到WSGI守护进程
    。如果我不使用
    守护程序模式
    ，则错误保持不变。如果我删除了
    WSGIApplicationGroup%{GLOBAL}
    ，它也可以工作。事实上，我也需要深入的解释。
