Error with high reaction heat

I have a problem with solving the heat balance for high reaction heat (-165 KJ/mol, math interface). If I reduce the heat production with factor 100, the simulation works, otherwise I get an error "Undefinded value found. -Detail: Undefined value found in the stiffness matrix. There are 199 equations giving NaN/Inf in the matrix rows for the variable comp1.T. at coordinates: (0), (0.005), (0.01), (0.015),...."
Could anybody give me an advice how to handle this problem?
