Memory error when running with enrichment?

While testing combine (pristine) in a vagrant box

$ ./combine.py -e

Hmm, that is a first. Do you mind sharing some details on the vagrant box you stood up (or even the config) so we could try replicating this?

[juju4]

No problem, it's a pretty basic one

# -*- mode: ruby -*-
# vi: set ft=ruby :

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "ubuntu/trusty64"

  config.vm.provider "virtualbox" do |v|
    v.memory = 2048
  end
  config.vm.network "public_network", bridge: 'eth0'
  config.vm.network "forwarded_port", guest: 80, host: 9880

  config.vm.synced_folder "/path/1", "/p"
end

and after virtualenv for requirements and execution
combine without enrichment is ok
if I switched to 4GB, it's ok.

Maybe adding a warning?

I have noticed this as well, and it's an artifact of how we store everything in memory before writing to disk at the end of the job.
