The symmetric birth and death stochastic process on the non-negative integers x Z+ with polynomial rates x [12] x= 0, is studied. The process moves slowly and spends more time in the neighborhood of the state 0. We prove the convergence of the scaled process to a solution of stochastic di erential equation without drift. Sticking phenomenon appears at the limiting process: trajectories, starting from any state, take nite time to reach 0 and remain there inde nitely
