Linode "Lassie initiated boot" 是什么原因？

[ybian]

在Fremont机房，平时用得很少，只用个人网站和 VPN。发现隔几天就会收到邮件说「Lassie initiated boot」，ssh 登录上去看 uptime，貌似是重启了。但问题是，我是唯一的用户，而且确定我没有做任何操作，这是怎么回事？

机房在维护机器? 发个ticket问一下好了, 没什么大问题

你用的是l2tp的vpn吧？被GFW攻击了

@milkmeat 确实用的是l2tp的 VPN。

发 ticket 问了，回答如下：

It appears that your Linode is kernel panicking, which is causing the watch dog to reboot the Linode. You might want to log into your server and see if you can determine what is causing the kpanic. You should start with /var/log to see if you can track down the cause.

查看了 kern.log 的内容，看起来好像是xl2tpd进程出了问题。 在重启前后 kern.log的内容是这样的:

这是GFW干的吗？
