I suppose you are trying to perform postbuckling analysis (nonlinear). Does the solution converges if you try linear buckling? Is the material linear or nonlinear? How the contacts are defined? Identify the region by asking for newton raphson residual (say, 3) under solution information details and check where the residuals are high. This may give some insight. Also check whether linear buckling analysis converges or not.
