我在带有 uWSGI (0.9.8) 的 Ubuntu 10.10 (64bit) 上运行 Django 1.3 + Python 2.6。但是，偶尔会在 uwsgi.log 中发现一些奇怪的日志，报告 'getattr', 'isinstance' 没有定义。但它们不是 Python 的内置函数吗？为什么 Django 找不到它们？这种情况在 uwsgi 服务器重新启动时流量较低时并不常见，而在流量较大且服务器运行时间较短时经常出现。

我确定我的 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：最新版本的 uWSGI 似乎不再有这个了。

详细日志：

Can you try with the latest tip ? It looks like a reference counting bug that should be fixed in 0.9.9-dev

If you can confirm it solves your problem i will release an updated release with only this fix applied.

Many thanks for the report
