It's a rotating moving mesh case, right?

If so, your problem is that some of the cells are slightly skew to the radial direction. This can happen due to roundoff error.

Gather all the vertices on your sliding interface into a VSET, and use the VMOD command is a cylindrical coordinate system to make sure the radius is EXACTLY what it should be.
