mee having same problem and checked /kill but now problem is not solved

I think this error results if you are using mass scaling in your model (DT/NODA/CST option) in your model and there is any factor causing the time step to decrease such as element distortion/penetration . Because the time step tends to decrease to very low values, too much mass is added to maintain the minimum time step,which results in this error. I suggest you to check for any penetrations through the interface or any element distortion happening in the model.
