  In this work we study the long time behavior of nonlinear stochastic
functional-differential equations in Hilbert spaces. In particular, we start
with establishing the existence and uniqueness of mild solutions. We proceed
with deriving a priory uniform in time bounds for the solutions in the
appropriate Hilbert spaces. These bounds enable us to establish the existence
of invariant measure based on Krylov-Bogoliubov theorem on the tightness of the
family of measures. Finally, under certain assumptions on nonlinearities, we
establish the uniqueness of invariant measures.
