Description
Possible regression of d2bd71d.
In CirlceCI environment starting rabbitmq:3 fails with:

My guess is that the entrypoint script fails to either read system's available memory or this info is not available.
When I pass RABBITMQ_VM_MEMORY_HIGH_WATERMARK=800MB to the container, it starts as expected.
