dockernetworking随机冻结

有时，我的专用服务器的所有networking都冻结（ssh也不能正常工作）。 它是随机重复的。

操作系统：Ubuntu 14.04.3 LTS

在服务器安装的docker集装箱，我看到在dmesg日志 ：

Docker信息：

• docker.io容器上的GPU访问
• 如何设置docker集装箱在专用networking上进行通信？
• 在连接到VPN的Docker容器中访问服务
• 将docker集装箱的输出stream量列入白名单
• 在Ubuntu 15.04上使用大量交换内存的Docker，为什么？

那么：是docker问题，还是上行链路接口坏了？
