IOError：无法写入数据 - Python Server

Question

知道为什么在将图像上传到服务器时会出现以下错误？！

[Tue May 21 23:44:01 2013] [error] [client 41.236.182.133] mod_wsgi (pid=9639): Exception occurred processing WSGI script '/root/AR_BROWSER/example/wsgi.py'.
[Tue May 21 23:44:01 2013] [error] [client 41.236.182.133] IOError: failed to write data

我一直在谷歌搜索很长时间，我没有任何帮助。

wsgi.py

import os
import sys

path = '/root/AR_BROWSER/example'

sys.path.append('/root/AR_BROWSER/example')
sys.path.append('/root/AR_BROWSER')
sys.path.append('/root/AR_BROWSER/example/app')
sys.path.append('/root/AR_BROWSER/example/static')
sys.path.append('/root/AR_BROWSER/example/static/uploaded_pics')

os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
