Question Using Geant4/MULASSIS with high energetic cosmic ray spectra, error message

Hello everybody,

I'm currently using Geant4/Mulassis for a paper study on shielding
from GCR on different shield materials.

I took my input spectra from the O'Neill galactic cosmic ray model,
that gives pointwise spectra from 1MeV to 10^6 MeV for the most
abundant species of the GCR, e.g. H,He,O,Fe etc.

During my runs through a 1g/cm2 Al shield layer I repeatedly receive
following error, while using an off-cutted spectrum up to 10GeV/n:

The runs were done using a Linux-exe Mulassis version from the Mulassis
site, built with Geant4 v8.1 (mulassis v1.15)

Does anyone know where this error comes from? I've done several runs
without experiencing it, recently I changed the macros using a slightly
varied spectrum.

Thank you very much!
Andreas
