Using a three-dimensional Vlasov code we investigate the unstable
generation of waves and reconnection in thin, collisionless
current sheets with guide fields and in magnetopause-like
configurations. The amplitude of the saturated waves appears to
critically control the moment of initiation of reconnection, it
determines the mode of reconnection, whether it is essentially
two-dimensional or three-dimensional as well as the reconnection
rate. In the guide field case of non-antiparallel reconnection a
transition from regular, well structured, to patchy reconnection
and percolation is possible, but in the asymmetric
magnetopause-like case we recover the formation of islands
reminding flux transfer events.
