Problem with prism cells
 

Hello,
I am modeling compressor stage and using a fairly standard process in ICEM CFD 15.0.
Geometry clean up --> surface mesh using octree-->Delaunay for vol --> mesh inspection and merging/moving nodes as per need --> make consistent and flood fill --> check mesh --> prism layer.

In my earlier models this approach worked just fine. I am doing mesh independence study now and this problem has surfaced. I get below pasted errors and then i can't export the mesh in CFX (gives the error: not able to generate the valid mesh elements).

Before generating the prims, default check mesh shows no errors (except multiple edges, which are intended in model).
I was wondering if anyone could share inputs on what might be wrong with model.
How can i see these element number mentioned in the error log in ICEM screen and also if i could get any pointers on the direction to mitigate this situation would be highly appreciated.

Thank you and I look forward to response.
