nonlinear optimization problem with constraints

Hello.I have an nonlinear optimization problem with constraints. I realy need help. I am using a package problem to solve this problem. However, although the program finds a solution without an error( since tolarance values are satisfied), when I check the constraints values , O see that some constraint values are not satisfactory (some constraints are realy close to zero which is satisfactory, but some are not close enough to zero).

There are 5 unknowns and 4 constraints. So this system has infinitly many solutions. I just want which solution makes the objevtive function minimum.

I don't have a much optmization background. I just want to determine among solutions(where the constraints are close enough to zero) which one makes the objective function minimum. As I mentioned, my priority is constraints to be satisfied satisfactorily.

I don't know how to searh this subject. I studied some nonlinear optmization resources. However all terminates when the tolareance values are close to zero not each of the constraints close to zero. Is there a way to control the closenes of the constraint to zero. If there is a way, I will be very glad for recomendaton of some resources. At least if this subject has an special name in the literature, I want to leaarn it.Thanks a lot. Best regards.
