Error in Cannot correct 4-momentum of cascade particles

Hi experts.
**I tried to simulate high hadron beams for high energies in the water phantom. **
**I am faced with this error in the terminal. I changed physiclist differently. I used hadronic examples physiclists in geant4 but it didn’t work. **
please help me.
I used Geant4 version 11.01

Can you please try to run an hadronic test of Geant4, without changing anything?
even the advanced example hadrontherapy would be fine.

Thank you

thanks. I did it, run had03 example even with higher energies and 10^8 particles. it is ok.

Generally, when I run my program with high-energy tritium or deuteron beams with particle number (10^8), I see this error. but if I use less incident particle numbers like 10^7, it works fine.

Not sure. It is strange. if the problem is visible with a Geant4 example, my suggestion is to submit a report to bugzilla,

Can you please submit a bug report to keep track of this bug? The code hits a rare condition causing an exception, or crash; its a real bug, curiously seen independently by two users. I am trying to understand the cause, and for now only have a workaround to avoid a crash.

Thanks. I tried to sign up to report the bug. Unfortunately, they need preauthorization, so I can’t report it.

I have the same issue, is there anything new? Otherwise, @gunter, can you please share the workaround you mentioned?
