I've put two identical ropes side to side, both with default settings. One of them with 2000 kg per particle, the other with 0.002 kg per particle. Both result in identical simulation, frame per frame.
See:
Obi's sequential solver is momentum conserving, both linear and angular, so there's absolutely no way increasing the mass of a rope would increase its energy. Make sure adjacent particles are not colliding with each other or with some object during simulation, as constraint fighting might cause unphysical effects.
If you can provide a sample scene that exhibits the behavior you describe, send it to support(at)virtualmethodstudio.com
