自由切换python脚本errno 10无子进程

Question

我在使用django.db模型在dialplan内部运行freeswitch和一些python脚本时遇到了一个问题。无论何时启动，它都会导致错误：

freeswitch@ubuntu> 2013-08-15 06:56:08.094348 [ERR] mod_python.c:231 Error importing module
2013-08-15 06:56:08.094348 [ERR] mod_python.c:164 Python Error by calling script   "fs_scripts.ringback": <type 'exceptions.IOError'>

编辑:导致错误的行是从django.db导入的简单代码：

 from django.db import models

整个设置已经在一些我无法访问的服务器上运行，所以django应用程序或脚本似乎没有任何问题……

任何帮助都将不胜感激，因为我已经没有办法解决这个问题了…

我不知道你的性能和可扩展性要求，尽管软交换有实时要求运行rtp流和信令。所以在mod_python下运行django应用程序并不是一个好的解决方案。此外，这与python解释器直接不同，有些东西不能工作。您可以在此处查看mod_python问题：mod_python issues

我建议您在客户端/服务器架构中拆分您的python解决方案。在mod_python下运行的脚本将向您的Django应用程序发出查询。这样你将摆脱Freeswitch方面的复杂性，获得可伸缩性，提高性能，并最有可能让一切正常工作。
