自从升级到引入 systemd 的 Debian 8 (Jessie) 后，我的系统日志错误中出现了这篇文章的标题。

远程 ssh 登录开始

客户端正常连接，客户端没有错误。

现在退出远程 ssh 客户端后...

系统详情

我正在运行的内核是当前的 Debian 内核，3.16.0-4-686-pae（即 >3.4）。

任何想法这个问题是什么，是否严重，我能阻止它吗？

    答案在日志输出的下一行：

    10:33:51 pap1 systemd[12228]: Failed to make us a subreaper: Invalid argument 10:33:51 pap1 systemd[12228]: Perhaps the kernel version is too old (< 3.4?)

    你的内核太旧了。
