我的安装了 gnome 的 Ubuntu 服务器几乎每天都会在同一时间重启或崩溃。
该服务器用作无头服务器，安装了 GNOME，可直接在服务器上运行一些脚本并检查数据，以及使用一些 IDE。为此，使用咖啡因打开虚拟 HDMI 插头以防止屏幕进入睡眠状态，因为我认为重启问题与此有关。
我尝试过暂停内核更新（我检查时发现问题出在哪里last reboot）
reboot system boot 5.15.0-46-generi Fri Sep 2 05:04 still running
reboot system boot 5.15.0-46-generi Wed Aug 31 05:03 still running

reboot system boot 5.15.0-46-generi Tue Aug 16 09:07 - 17:29 (14+08:21)
reboot system boot 5.15.0-43-generi Tue Aug 16 05:03 - 09:07 (04:03)
但问题是内核不再更新，服务器不断崩溃。
当我问who -b
system boot 2022-09-02 05:04
我还检查了一些 cronjobs，但系统没有，所以我检查了一下systemctl list-timers --all

重启时我没有发现任何异常。
我对这个问题很绝望，我开始考虑一个有故障的组件，任何帮助都会很好。
谢谢
