Floating point error

Hello guys,
i am having similar problem, I am working on combustion of CH4 in an ion transport membrane, when i tried the cold cases, it converged but as soon as i activated the volumetric, there is divergence, i have errors like:

temperature limited to 1.000000e+000 in 4 cells on zone 2 in domain 1
temperature limited to 1.000000e+000 in 4 cells on zone 2 in domain 1
temperature limited to 5.000000e+003 in 2759 cells on zone 2 in domain 1
temperature limited to 1.000000e+000 in 832 cells on zone 3 in domain 1
temperature limited to 5.000000e+003 in 1161 cells on zone 3 in domain 1

absolute pressure limited to 1.0000+000 in 448 cells on zone 2
absolute pressure limited to 1.0000+000 in 291 cells on zone 3
absolute pressure limited to 5.0000+010 in 1 cells on zone 3

Error: Floating point error: invalid number

Error Object: ()

kindly help me out, i still have a long way to go in my thesis
