Should I worry about this warning?

I am simulating CT-Dicom Images (37 slices) and hitting it by 5 million events of proton and got the following error.

------- WWWW ------- G4Exception-START -------- WWWW -------
*** G4Exception : GeomNav1002
issued by : G4Navigator::ComputeStep()
Track stuck or not moving.
Track stuck, not moving for 10 steps
in volume -Detector_two_stack_v203Geom_vol- at point (-2.94654,0.122429,-8.43648)
direction: (-0.0160609,0.671728,-0.740624).
Potential geometry or navigation problem !
Trying pushing it of 1e-07 mm …Potential overlap in geometry!

Question here: Is it has any influence on my results because the same Phantom dimensions are used for simulation, but PMMA not CTDicom images, and I did not get this error.

Thanks in Advance

Hi Moham! Have you solved the problem? I met the save exceptions.
