Just a few comments on your the physics as you say are using - G4HENeutronInelastic is the high energy parameterized model, and 5 GeV is most likely too low an energy to use this. We generally do not use this below 30 GeV, and use G4LE... until then.
- Do you also include the neutron capture ( and maybe fission) from HP?
Of course I assume that you also added HP cross sections?
You could try one of our reference physics lists, at least to see if the looping is caused by your physics settings. The one similar to what you have would be QGSP_BERT_HP, or QGSP_BIC_HP using teh Binary Cascade instead of Bertini; both also use QGSP instead of the parameterized models for high energies.
