Nik*_*ita 6 networking ubuntu docker
有时，我的专用服务器的所有网络都冻结了（ssh 也不工作）。它是随机重复的。
操作系统：Ubuntu 14.04.3 LTS
在服务器上安装了 docker 容器，我在dmesg 日志中看到：

那么：是 docker 问题，还是上行链路接口坏了？

您正在运行一个已知无法与 Docker 配合使用的系统。 从错误来看，它只是重复地使系统崩溃。
您可以首先升级到 Ubuntu 16.04 TLS（撰写本文时的最新版本）。祝 Docker 正常工作，默认设置通常不会。
基本上，Docker 在大多数系统上都完全崩溃并且不稳定。请参阅这些文章以获得长而戏剧性的版本。
