I believe that using the spring to stabilize model is more to help you find out where you don't have adequate restraints rather than to give you a good solution. After using this option, check your model to see where you DON'T have a restraint, but DO have unexpected stresses. This should help you understand what additional restraints are necessary.

To expand on this, the error is usually caused by an insufficiently restrained model. Soft springs may solve this but should be used a last resort or, as Peter suggested, as a way to find the direction that needs more restraint. You should try your best to fully restrain your models. If you think adding additional restraints will overstiffen the model, make sure your problem is force/moment balanced before relying on soft springs. They are not meant to react out a measurable load but to provide numeric stability in an otherwise force balanced model.
