amazon web services - docker dead but pidfile exists -

I was working on the AWS example on the Docker and it was working fine. One day, Docker stopped working. When I restarted the Doker "Service Docker Start", it started and "Service Docker Status" did not execute the message and the Docker commands "Docker is dead but the PDF file exists". When I inspected the log file, the following messages were shown:

  msg = "+ Jobs ServicesP (Unix: ///var/run/docker.sock)" msg = "Unix Listening to HTTP (/var/run/docker.sock) "msg =" No more loopback devices are available. "Msg -" Loopback mounting failed " 

To start the Dock For, I deleted the pid file from /var/run/docker.pid, /var/run/docker.sock, and docker / var / lock / subsus / docker and restart docker but no gain still gives the same error "Doc die But pidfile exists "
