神秘的 Debian 8 随机重启

  • 772

我有一个随机重启的 Debian 8 服务器。我试图从以前的引导中查找 journalctl 日志（日志是持久的），但什么也没找到：

$ journalctl -b -1 -e

尝试 grep 遍历所有日志（重新启动、关闭、关闭、关闭、重新启动、恐慌） - 没有任何帮助：

$ grep -rn "reboot" /var/log

我能够在几个 GCP 和 OVH（VPS，专用）节点上重现它。尽管一些具有类似设置的节点工作得很好。

$ last reboot

日志中没有任何内容表明谁触发了重新启动，没有内核恐慌，这非常奇怪。

我尝试按照服务器神秘重启/sbin/shutdown中的建议进行替换，但似乎没有人运行它。

重启后的 Journalctl 日志：https ://pastebin.com/raw/AmkNVs66

请建议我如何进一步调试它。

    随机重启是由内核恐慌引起的，尽管没有日志表明它。安装和配置 kdump 后，我得到了一个堆栈跟踪，帮助我识别问题。不明显。
