Default Centrifugal Pump: cells with high values of pressure

dmaz is on a distinguished road
I'm running the analysis of a centrifugal pump in OF, the geometry is the same reported in the the Ansys.CFX tutorials "Chapter 28: Drop Curve for Cavitating Flow in a Pump".

I have set the analysis with the SRFSimpleFoam solver, cyclicAMI condition for the periodicy and rotatingWall for the stationary-wall.

After 1000 iterations, I noticed that some cells, near the intersection between the inlet and the shroud-wall, assume high value of pressure and velocity respect the correct field.
I have also seen the error in another case.
Is this a common error in OF? What can be the cause of the error?
Thanks in advance,
