docker启动错误

docker 启动报错
docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "process_linux.go:301: running exec setns process for init caused “exit status 40"”: unknown.

解决：
echo 1 > /proc/sys/vm/drop_caches

echo “vm.min_free_kbytes=1048576” >> /etc/sysctl.conf
sysctl -p

再次启动没有报错
