Observations: The colour water rises in level and the manometer shows the root pressure by the increase in mercury level. Conclusion: The water level increases as a result of root presure. Each root either refers to an object on the managed heap or is set to null. RCA assumes that it is much more effective to systematically prevent and solve for underlying issues rather than just treating ad hoc symptoms and putting out fires.
