  We present high resolution 2D and 3D simulations of magnetized decaying
turbulence in relativistic resistive magneto-hydrodynamics. The simulations
show dynamic formation of large scale intermittent long-lived current sheets
being disrupted by the tearing instability into plasmoid chains. These current
sheets are locations of enhanced magnetic field dissipation and heating of the
plasma. We find magnetic energy spectra $\propto k^{-3/2}$, together with
strongly pronounced dynamic alignment of Elsasser fields and of velocity and
magnetic fields, for strong guide-field turbulence, whereas we retrieve spectra
$\propto k^{-5/3}$ for the case of a weak guide-field.
