Hi,

1) It is possible to reproduce particular event.
2) Error may be connected not with the event but be a product of
   integration over many events.
3) Is it possible to repeate the problem with "/tracking/verbose 2"?
   even if the output file will be large, one can find inside an event
   with problem and study what happend: in which process secondary has
   kinetic enery more than initial kinetic energy if any.
