Docker-images: Can't run the database container (DBCA, memory allocation problem?)

[AdrianLoer]

Hey, I was following your guide at https://blogs.oracle.com/developer/entry/creating_and_oracle_database_docker

and running the container after building the image with

docker run -p 1521:1521 --name oracle oracle/database:12.1.0.2-ee
this results in the following error which afaik is different from the other ones in open issues.

Does anyone have an idea how to solve this?

I closed this, the problem was as dumb as it could be:
Forgot I am on mac and had set the vm memory for some reason set to 2gb, indeed a memory issue...
