Djangofile upload偶尔失败

我试图移植我的第一个Django 1.0.2应用程序在Apache + mod_python 3.3.1 + python 2.6.1（所有在64位模式下运行）在OSX / Leopard上运行，并且上传文件时遇到偶尔的错误这在使用Django开发服务器进行testing时并不存在。

上传代码与Django文档中描述的类似：

class UploadFileForm(forms.Form): file = forms.FileField() description = forms.CharField(max_length=100) notifygroup = forms.BooleanField(label='Notify Group?', required=False) def upload_file(request, date, meetingid ): print date, meetingid if request.method == 'POST': print 'before reloading the form...' form = UploadFileForm(request.POST, request.FILES) print 'after reloading the form' if form.is_valid(): try: handle_uploaded_file(request.FILES['file'], request.REQUEST['date'], request.REQUEST['description'], form.cleaned_data['notifygroup'], meetingid ) except: return render_to_response('uploaded.html', { 'message': 'Error! File not uploaded!' }) return HttpResponseRedirect('/myapp/uploaded/') else: form = UploadFileForm() return render_to_response('upload.html', {'form': form, 'date':date, 'meetingid':meetingid}) 

此代码通常正常工作，但有时（比如每10次上传一次）以及相当长的等待时间后，会失败，并显示以下错误：

我试图运行一切使用mod_wsgi没有区别。

• 无法浏览到我的EC2实例
• 运行没有扩展名的PHP，而不使用mod_rewrite？
• 启用Apache ANT的javacdebugging
• 使用objective-c进行Web应用程序编程？
• Apache端口转发

有人知道我在做什么错吗？

在此先感谢您的帮助！

更新：

虽然我成功地上传了大文件（60+ MB），但是当它失败的时候失败了，与上传的大小没有明显的关系，也就是上面成功上传的10kB文件也失败了。
