Я пытаюсь перенести свое первое приложение Django 1.0.2 для запуска на OSX / Leopard с Apache + mod_python 3.3.1 + python 2.6.1 (все работают в 64-битном режиме), и иногда возникают ошибки, когда загрузка файла, которого не было при тестировании на сервере разработки Django.
Код для загрузки похож на тот, который описан в документации Django:
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})
Этот код обычно работает правильно, но иногда (скажем, один раз каждые 10 загрузок) и после довольно длительного времени ожидания происходит сбой со следующей ошибкой:

Я пытался запустить все, используя mod_wsgi, и без разницы.
Кто-нибудь знает, что я делаю не так?
Заранее спасибо за помощь!

Обновлен:
Несмотря на то, что мне удалось загрузить большие файлы (более 60 МБ), при сбое происходит сбой без очевидной связи с размером загрузки, т. Е. Происходит сбой и с файлами размером 10 КБ, которые были успешно загружены ранее.
