Negative Turbulence K.E./Dissipation

Hello,
I am running a computation on compressible turbulent transonic flow. I am getting warnings of "negative turbulence K.E.", "negative dissipation" and "out of bounds scalar variable enth". Can anyone kindly explain what they are about and how do you get rid of them. I am using K-e/high reynolds number turbulence model, UD scheme for velocity,pressure, turbulence and temperature and MARS scheme for density, with relaxation factors as low as 0.000001. Thanks |
