Docker container can't invoke

In our centos 7 machine, i can’t able to invoke an docker container, then did the ps -auwxx | grep migrations , don’t know in which service is running in root user .

I googled and found the link http://askubuntu.com/questions/85463/high-cpu-usage-without-a-process-to-blame-what-is-migration-x

Could you please let me know, what process is this .? Is this related to docker .?? How to resolve this error permanently .???

Your suggestions is highly appreciated.

Thanks,
