Since Geant4 10.3 we reorganise various protections in different parts of Geant4 physics models and introduced tracking cuts per particle into ionisation process. This cut is needed to avoid tracking of very low energy particles with very small step size happens in LHC simulations. The default tracking cut is 1 keV. There are UI command allowing to change it to whatever value, for example, to zero:
/process/em/lowestElectronEnergy 0.0 MeV /process/em/lowestMuHadEnergy 0.0 MeV
