avocado-submit crash on startup with insufficient memory

[davidonlaptop]

We need to validate that the image is OK to rule out that the problem is only related to missing memory on my old laptop.

Steps to reproduce:

1. Build the image: docker build --rm=true -t avocado .
2. Run the container: docker run --rm=true avocado

Error:
