Do you mean that you used non-parallel ForceContainer with OpenMP-enabled simulation run with multiple threads? If so... threads could have been overwriting each other's data. https://www.yade-dem.org/doc/prog.html#forcecontainer explains why threads must have separate data (unless you want to use locking, which will be very very likely much less efficient).
