添加具有 ImageField 的表单后，我的网站上出现 MemoryError。该代码在我的开发服务器（OS X 10.7.4）上运行良好，但在我的暂存环境（CentOS）中失败。

对于看起来类似的问题，我有点不愿意使用此处提出的解决方案：Python ctypes MemoryError in fcgi process from PIL library。它改变了 python 本身——这似乎不利于长期维护。

我对如何调试这个有点一无所知...请帮助我治愈我的无知...

这是回溯：

通过让 mod_wsgi 在用户 ID 下运行，使用https://bugzilla.redhat.com/show_bug.cgi?id=717404解决了这个问题。
