[CentOS] Restarting docker daemon fixes network problem inside containers

We are building docker containers on Centos 7 based machines. Sometimes the
docker being built cannot install packages because of some kind of network
failure. I just found that restarting the docker container fixes the
problems and the builds are successful.

Does anyone have a clue what the root cause of this might be?
