Error when running a particular model for right handed neutrino decay

Hello,
We are using a toy model of right handed neutrino and colored scalar (that couple to quarks via qNphi and qq phi vertices). We generated the model file using FeynRules, and we were interested in looking at available decay channels of right handed neutrino in this model. We have succeeded to replicate analytical results for 2 body and 3 body decays that involve phi and N, and generate one 4-body and 5-body decay. However, we ran into the problem when we were trying to compute width for a process nn > w- bbar sbar dbar. Namely, if you run MadGraph for this decay channel for mN=150 GeV and mphi=90 GeV the MadGraph outputs a value for the decay width. However, if you run the same scan but for mN=170 GeV and mphi=90 GeV we get an error that we do not understand. Can you help me understand what is breaking down in the calculation? I attach the log file, let me know if you need any other information
