Hello, every one!

First of all, I am new in OF, and I am not very good at English. This is my first time to asking on this website. Sorry about that.(and the title)
I have come to a problem lately when I solved a case using reactingFoam. the geometry is quite simple, just like a channel with premixed CH4 flows in and products flows out, there should have a flame attach to part of the wall with high temperature.

but I keep coming to an error, temperature very high and dt very short, so my program stuck and can not calculate any further.


the error:


--> FOAM Warning :
From function janafThermo<EquationOfState>::limit(const scalar T) const
