java.lang.AssertionError: Docker environment has more than 2GB free

I have been creating tests for my program that uses docker. And everything was working well until suddently I face this problem at the start of any test

ℹ︎ Checking the system...
    ✔ Docker version is newer than 1.6.0
    ✘ Docker environment has more than 2GB free

Test ignored.

The class MongoDBTest starts with:

public class MongoDBTest
{
  @ClassRule
  public static GenericContainer mongodb = new GenericContainer("mongo:3.6")
          .withExposedPorts(27017)
          .waitingFor(Wait.forListeningPort());

With line 24 being the one where I call "new GenericContainer"

I cant figure out what can be the problem. My computer has 16GB of RAM, out of which about 10GB should be free. I ran the test about 10 times successfully today before the problem arose, and I have tried restarting computer but it didnt help.
