正常运行以下命令
sudo docker run --rm busybox echo helloworld

我把这个写入crontab中，每分钟执行一次，有几率出现如下错误（如果更加频繁执行docker run那出现错误的几率更大，目前一分钟一次的出错概率大概是2天一个error）

原因：基本还是docker不稳定造成的，并行快速的运行container的时候，有几率出现如如上错误
与之有关的issue如下：

如果哪位发现docker解决了这个issue了，请帖出docker version和机器信息，多谢~
@Tom哥，说 rhel6.5 内核版本2.6.32，docker version 1.1.2, 没有这个问题
@IT人， 说ubuntu 14.04 centos7.0 7.1，没有这个问题
我还没有验证过。
