note that there is also a message

*** Note: Step information might not be properly updated.”

note also that we just change from Geant4 11.3.2 to Geant4 11.4.1

Dear All,

I checked I have the same Pb with Geant4 11.3.2

thanks for help and feedback

The event id in Geant4 is an int, and so it is limited to 2,147,483,647.

If you need to run more events you should probably divide them in different runs (calling /run/beamOn multiple times with a smaller number of events)

Hi Davide

Thanks for your help

but I asked beamOn 2e9 so below the limit 2,147,483,647.
