Why does fmincon's constrviolation converge at a specific value?

This is kind of a general doubt. I am performing non linear optimization with a bunch of non linear inequality constraints, linear equality and inequality constraints. The constrviolation field of fmincon's output in my problem converges at 0.05 no matter where its initial value is. What might be the reason for this? What are some possible places in my code I should look at to correct this error to ensure a smaller value of convergence?

You could reduce the ConstraintTolerance input parameter. You don't want to make it zero, however.
