docker执行错误：rpc错误：代码= 13

我有一个错误，当我做dockerexec -it容器ID bash但容器是up.the容器的mysql可以访问。在同一台计算机（linux / centos7）两个其他容器起来，运行良好..

rpc error: code = 13 desc = invalid header field value "oci runtime error: exec failed: container_linux.go:247: starting container process caused \"process_linux.go:75: starting setns process caused \\\"fork/exec /proc/self/exe: no such file or directory\\\"\"\n"。 

docker守护进程日志:( ps：磁盘存储容量没问题）
