It's not too clear from your question what T (s) is, but I'll assume from context that it is the closed-loop transfer function, i.e. T = Gp / (1 + Gp). The poles of T are purely imaginary ( +-j*sqrt (5)) and so T is "marginally stable" or more intuitively you can think of it as a mass on a spring- an oscillator.
