无法对任何正在运行的 Docker 容器执行命令

我可以用 启动容器docker run，并且它运行没有问题。但是我现在无法docker exec对正在运行的容器执行任何命令。错误如下：

rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:262: starting container process caused "process_linux.go:81: executing setns process caused \"exit status 16\""

我尝试重新安装 docker-ce，但没有帮助。

操作系统：Ubuntu 14.04

Docker 版本：17.06.0-ce

调试日志：（执行ls命令）

欢迎任何想法。

使用systemctl restart docker修复了这个问题。
