我有一个在Docker compose环境中运行Nginx，Django，Postgres和Golang微服务的VPS，最近我注意到它一直达到100%的CPU利用率，并且不再工作。我怀疑这可能是由于DDoS攻击或奇怪的gunicorn行为。

**VPS操作系统：**Ubuntu 22.04.2 LTS
意见：

高CPU使用率从昨天（24小时前）开始。

采取的步骤：

设置和配置ufw，和一个digitalocean防火墙。

当访问域时，它直接达到CPU限制。我正在实现一些新的功能，这就像一个魅力（本地），但我想不出会做这样的事情。实际上，我也回滚了所有内容，遇到了同样的问题。
我被困在哪里看。
会很感激任何提示。
PS：如果你需要更多的信息，请在评论中告诉我。我不想再拖下去了。
在此先谢谢您！
