divergence detected in two phase flow after thousands of iterations?!

I am simulating a two phase flow in a pump, air and water, and i am using Euler Euler multiphase model...
i reduced my under relaxation factors to 0.1 and 0.2 and the model runs fine in the begining... after thousands of iterations it just explodes, and gives the error message " divergence detected" or the temperature or turbulent viscosity exceeded the limits...
when i turn off my energy equation and use constant density gas, it does not do that... however i need to use ideal gas with the energy equation...
