Hi, 2 cores and 10GB should be enough. 4GB would probably do as well. The tests are expected to take several minutes. Running mysql, postgresql, h2, mongo suite takes another several minutes.
Is the freeze reproducible or it is just an accidental one? If you experience a freeze, it would be nice if you could collect several "kill -3 <java_process_id>" and "jstack -m <java_process_id>" thread dumps so we can identify the action in question and fix it. Vladimir
