Mongo cannot initAndListen

We’ve been seeing some issues with our circle workflowsa since yesterday evening. All mongo images fail to come up and this is what we see in the logs.
We currently use the circleci/mongo:3.2-ram image.

This is causing all our workflows to fail. any idea what might have changed since yday?

Turns out the non ram image circleci/mongo:3.2 seems to work. Still not sure what caused the problem though
