You must have turned verbosity for the OpBoundaryProcess on, probably with commands from G4OpticalPhysicsMessenger:
Commenting this out or change it to:

The property the program wants has been defined by you in a range that does not overlap with the photon's energy that's being propagated! You should be mindful of that - why is this happening - but the program does use the nearest value you provided.

With verbosity you get this line when a photon reflects. The propagator does a 'reallocation step' that has zero step length before continuing with another finite (>0) step. This is normal and expected. In fact, missing this reallocation step upon reflection is an indication that something is wrong with your geometry definition and you have an overlap.
