We study the lattice spacing dependence of meson spectral functions
calculated in quenched QCD with domain wall fermions as well as clover Wilson
fermions in quenched and partially-quenched QCD. We conclude that for lattice
spacing $a \le 3$ GeV all excited states appearing in the spectral functions
are lattice artifacts.
