IOError: 请求数据读取错误

Question

我在进行Ajax文件上传时，常常遇到一个错误，叫做IOError: request data read error。比如说，每上传5个文件，至少有3个会出错。

其他人似乎也遇到过同样的问题。例如：

还有一些其他的观察：

这绝对不是我的网络连接或浏览器的问题。所有浏览器，包括Chrome、Firefox和Opera，都出现了这个问题。
我在使用django 1.1.1 Apache/2.2.14 (Ubuntu) mod_ssl/2.2.14 OpenSSL/0.9.8k mod_wsgi/2.8 Python/2.6.5，运行在Lucid系统上。
文件大小也不是问题。有时候我能上传超过1MB的文件，但却在上传180KB的文件时失败。
