The fmean residual falls to around 1e-20 over the course of  around 15 iterations, and then fluent crashes with this error. I am using DPM and non pre-mixed combustion. I tried the same setup with the EDC combustion model and I didn't get the error, but would rather use non pre-mixed combustion model

How much evaporation did you see before the solver failed? How does the combustion mechanism differ between the two models: ie what core assumption is different that could explain the problem?
