Function called when *NOT* at a boundary

Hello,
I am getting a warning message (many times):
G4Exception:GeomNav0003
issued by G4Navigator::GetLocalExitNormal()
Function called when NOT at a boundary
This is just a warning message.

I note this issue cropped up about 6 years ago and is discussed here:

However, since its just a warning message, can I just switch it off (I presume by reducing verbosity somewhere), or do I need to pay heed to it ?

Thanks
Chris
