Question

我正在使用uWSGI（0.9.8）在Ubuntu 10.10（64位）上运行Django 1.3 + Python 2.6。但是，我偶尔会在uwsgi.log中找到一些奇怪的日志，报告“getattr”，“isinstance”未定义。但它们不是Python的内置函数吗？为什么Django找不到它们？当uwsgi服务器重新启动时流量较低时，这种情况不常发生，并且当流量很大且服务器运行一段时间时，很多时候会出现这种情况。

我确信我的django应用程序没有任何问题，但我不确定这是否是Django，uWSGI甚至Python 2.6中的错误。

更新：uWSGI的最新版本似乎没有这个。

详细日志：

你能试试最新的小费吗？它看起来像一个引用计数错误，应该在0.9.9-dev

中修复

如果您确认它可以解决您的问题，我将发布更新版本，仅应用此修复程序。

非常感谢报告
