Alice It's telling you that you're geometry titled "FMA37686:grp1Shape" has poorly conditioned triangles.
If you select that geometry and run the Mesh Analysis tool in the Ziva Tools Menu, it will select the vertices of the problematic triangles.
Usually just running a polyAverageVertex on the selected vertices a couple of times will usually resolve an error like the one above.
Give that a try and let me know if you need additional help.
