我的服务器运行良好，但几周前，即使我删除了一些可能存在问题的应用程序，它仍然在夜间挂起，我猜想这可能是电源传输、某种奇怪的空闲状态或基于 cron 的原因。今天我打开了 syslog 文件，根据 02:17 的图像，出现了一些有趣的东西
4 月 5 日 02:17:01 家庭服务器 CRON[285582] (root) CMD (cd / && run-parts --report /etc/cron.hourly)
7:23 时我醒来，注意到并重启了服务器。下面是 crontab -e 文件，上面没有安排在服务器挂断时执行的任何操作。有人知道问题可能出在哪里吗？
sudo crontab-e：

编辑：我注意到的一件事是，当我在外面连接到它时，它整天都工作正常，当我回到家时，它使用 netatalk avahi 启动了时间机器备份，而我正在将一些文件传输到网络磁盘时它挂断了，我删除了 netatalk avahi 并使用 samba 的另一种备份方法，删除了一些我不再需要的旧 docker 容器，还更改了驱动器连接的集线器，它设法存活到凌晨 6 点 59 分，我检查了 kern.log，lidarr 的一个实例是挂断时最后一个工作的服务，所以我也禁用了它。让我们看看今天它是否会达到 24 小时而不挂断。
