运行 Ubuntu 14.04.2 LTS
我的服务器意外重启,并在系统日志中发现以下消息:

USB 键盘连接消息很奇怪,而且经常出现。它在重启前 3 分钟开始,每 30 秒重复一次。
这可能是数据中心的 KVM over IP 系统出现故障。我正在尝试与支持团队澄清这一点。即使重新启动后,它仍会每 4 分 30 秒出现一次。
我只是想弄清楚到底发生了什么?
我检查过
grep sshd.\*Failed /var/log/auth.log | less
我什么也没找到。而且也没有任何成功登录的信息。
这是什么Activating service name='org.freedesktop.systemd1'
意思?
