FEMAP buckling problem

Hi,
I hope that someone of you can help me.
I realized a model of a partition in sandwich material that is connected to the floor through 2 shock absorber and on the upper part with two pins. The shock absorbers have been modeled with damper/cbush with coincident nodes that connect throug rbe2(123) to the brackets connected to the partition. I attached a picture.
Now, I made a buckling analysis and I have an eigenvalue really low: 0,16 . The deformation vector that shows the buckling mode, reveals a strange displacement close of the lbrackets the maybe can be caused from rbe2.
I read that the material used in the buckling analysis have to be elastic. Is it maybe here the problem?
