env 部分引用了 REQUEST_URI

/favicon/proxied?XXXX.ico

我检查了 URL XXXX.ico，它是有效的并且可以工作，并返回了站点的 ico 图片，似乎是指站点 logo 图标。我注意到每次我打开论坛的任何页面时都会记录此错误。

这个错误是什么，它意味着什么，以及如何修复它？

不确定是否相关，但我也在日志中看到了这个错误，就在上面，引用了相同的图标 URL，但它只记录了两次，大约在 2 周前

DistributedMutex(“memoize_lock_FAVICONXXXX.ico”): held for too long, expected max: 1 secs, took an extra 3 secs
