local_dc was limited to 10 systems, but we are already running 10 systems on oaf0 with room for at least two more. mbuf also happens to max out at 10 or 11 systems. There were maximum 64 mbufs. At 5 mbufs per model + a handful of extras, 11 systems is pushing it.
This change increases max mbufs to 1024 and max local_dc systems to 64
Closes #421 (closed).
