Error - momentum, energy, and/or time was illegal

Hi
I am running an old code created 3-4 years back and used to run quite well. Now when I am running the code on same Geant4 virtual machine (Geant4.10.0), it is being aborted with following message

--------EEEE---------G4Exception-START---------EEEE----
G4Exception : TRACK003
issued by : G4ParticleChange::CheckIt
momentum, energy, and/or time was illegal
*Event must be Aborted
---------EEEE---------G4Exception-END---------EEEE----

Segmentation fault

please let me know how to handle this issue

Hello,

this information is incomplete, you need to understand, what is the primary particle and what interaction happens. This exception indicates some large non-conservation at a step. You may tray to use

/tracking/verbose 1

VI
