昨天，服务器可以正常工作，但是现在，以前可以正常工作的 URL 却显示：
404 Not Found
nginx
我正在使用 Linux 版本 2.6.32-754.35.1.el6.x86_64 ([电子邮件保护]) (gcc 版本 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC) ) #1 SMP 星期六 11 月 7 日 12:42:14 UTC 2020
访问日志给了我很多垃圾，例如：
Â@{¿â°•‚¹{÷‘„ÄJDFEp!…XD]q1QAñëM!§›a8©¢„´ÑduÛr,çõMjÖ:ç,76·ÇÌ;ˆÙÔA¢pn-)Ë

我看到了错误日志，但在过去 5 天内没有出现任何内容，错误日志文件在过去 5 天内没有被修改，所以我不确定除此之外我还需要检查什么。
我记得我遇到了一些有关清漆的问题，我想在重启之前和之后我能够解决它，但重启没有任何作用。
我在 php-fpm 日志中看到一件事：

就是这样，所以我想 404 可能是由于使用了太多资源。我该如何进一步调查？谢谢
该堆栈是 Nginx -> Varnish -> Apache -> PHP-FPM
我认为 cronjob 可能是问题所在，有没有办法禁用所有 cronjobs 而不停止浏览器请求的服务？
