This in error in the 2D integration routine. In one of the integrals, convergence was not reached. This happens occasionally and on average does not perturb the final results. However, NAG should exit in these cases with a soft failure (output a warning instead of a hard stop). That's how it was coded. It is set by the input ifail in the d01fcf function. Maybe there is a compatibility issue with the NAG version used at NERSC.
