Problem with energy residuals

I have a problem which is very strange for me and I've never experienced it before!
I'm working on a Rotor-Stator that modeled as periodic with periodic angle of 60 degrees!
when calculation starts, everything is ok! but when computing continues, the energy residuals increase and diverge!
and Fluent says:
"temperature limited to 1.000000e+00 in 89 cells on zone 41 in domain 1"
The interesting point is that in my case there isn't any source term,wall with constant heat flux or constant temperature or something like them! but sometimes temperature range is between -50000 K(!!) to 50000 K!
while it's just a rotary flow!
Does anyone have a solution?
What do you think is the problem?
