Pipeline hangs on nose2

[Paddy McCrudden]

I have a pipeline specified by the following file. 

image: python:3.6.2

pipelines:
  default:
    - step:
      caches:
        - pip
      script: # Modify the commands below to build your repository.
        - pip install -r requirements_version.txt
        - nose2

This seems to work fine. But when I replace the nose2 with the full suite of tests by:

        - nose2 --plugin nose2.plugins.doctests --with-doctest

The system seems to hang. I can confirm that the tests run successfully in a container running on my desktop. It just seems to fail on bitbucket.

This has been mysteriously resolved. Not aware of any changes on my code base that impacted it.
