Python Django文件上载偶尔失败

我正在尝试移植我的第一个Django 1.0.2应用程序，在OSX/Leopard上运行Apache+mod_python 3.3.1+python 2.6.1（都在64位模式下运行），在上载Django开发服务器测试时不存在的文件时，我偶尔会遇到错误

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})

此代码通常工作正常，但有时（例如，每10次上载一次）在经过相当长的等待时间后，会出现以下错误：

我试着用mod_wsgi运行所有的东西，没有任何区别

有人知道我做错了什么吗

提前感谢您的帮助

虽然我成功上传了大文件（60+MB），但当上传失败时，与上传大小没有明显的关系，也就是说，之前成功上传的10kB文件也失败了

文件有多大？上载脚本超时可能需要足够长的时间，因此请尝试增加该脚本的执行时间。

我将查找异常值

Client read error (Timeout?)

这似乎很奇怪。试着用mod_wsgi阅读

，这样Firefox就不会有问题了

将我的研究局限于Apache和Safari之间的交互问题，我偶然发现了Apache的这个bug报告，它描述了一些与正在发生的事情非常相似的事情，而且它显然仍然是开放的。读了这篇文章，我想到了尝试禁用keepalive，尽管我需要对它进行更广泛的测试，但问题似乎已经解决了

一个简单的例子：

BrowserMatch“Safari”nokeepalive

---

在Apache配置中做到了这一点。

这里有很长一段时间没有回答，但我自己经历了这一点，并尝试了一些方法来解决它。在我看来，如果有人在上传过程中取消了下载（或断开连接），就会发生这种情况

---

您可以自己尝试一下，看看这是否是导致“IOError:请求数据读取错误”的原因：上传一个足够大的文件，您可以从计算机或路由器上拔下以太网电缆。请稍等，看看是否出现错误。我每次都这么做

对不起，不是这样的：我可以上传大文件，但小文件仍然无法上传。见更新的问题。无论如何，谢谢。我得到了这些数据的例外情况。”HTTP_USER_AGENT'：“Mozilla/4.0（兼容；MSIE 8.0；Windows NT 5.1；Trident/4.0；.NET CLR 2.0.50727；.NET CLR 3.0.4506.2152；.NET CLR 3.5.30729）”，
