Abstract
We add memory effects to the master equation describing a harmonic oscillat or embedded in a reservoir. Solving the time evolution exactly, we show tha t the model is sensible only in the Markovian limit. Thus we issue a warnin g against indiscriminate introduction of memory effects in master equations and call for a systematic method to obtain corrections to Markovian time e volution.
