Docker - R creates multiple processes

I'm creating a docker container and I'm installing R in it.

The problem is, that when running R in the container, the main R process create ncores - 1 subprocesses.

So when running the docker on my laptop with 8 cores, I get 1 R process and 7 R subprocesses.

I also tried to configure my Docker file similar to this:

https://github.com/rocker-org/rocker/blob/eeb9c8a5f416f7cfe982734440e39fa72abbcb33/r-base/Dockerfile

but is still not working.

Docker-file:

FROM ubuntu:14.04

RUN sed -e 's/archive\.ubuntu/at\.archive\.ubuntu/g' -i /etc/apt/sources.list
RUN apt-get update
RUN apt-get -y install libatlas3-base
RUN apt-get -y install libopenblas-base
RUN apt-get -y install r-base
RUN apt-get -y install r-base-dev
RUN apt-get -y install apt-utils

RUN echo "deb http://cran.cnr.berkeley.edu/bin/linux/ubuntu/ trusty/" >> /etc/apt/sources.list
RUN gpg --keyserver keyserver.ubuntu.com --recv-key E084DAB9
RUN gpg -a --export E084DAB9 | apt-key add -
RUN apt-get update
RUN apt-get -y --with-new-pkgs upgrade

Did someone encountered this problem?

I don't know why, but the whole problem was caused by installing libopenblas-base.

After removing the line 

RUN apt-get -y install libopenblas-base

everything worked fine!
