Excessive displacement error on part with symmetry constraints.

I am trying to analyze the part shown in the images.  When I run it I get the error "excessive displacement".  I have attached the simulation properties and some results.

Is there something I am doing incorrectly, or a better restraint?  I am after the stress plot, but I do not know how well I can trust those numbers when the displacement seems to be screwing up.
