A bit more research points to an old problem, marked as fixed:
http://defect.opensolaris.org/bz/show_bug.cgi?id=15761

This box did have a pkg/server (startd/duration=child) instance
which did not start well and was left astray. From what I see
now, a daemon is started and in particular grabs the TCP port,
but SMF thinks the service has failed and restarts it. Further
invokations fail due to busy port, but the service does not go
into maintenance. I see svc.startd occupying more RAM at a rate
of about 1Mb/1-2mins (glancing at top).

The symptomatic part can be fixed by simply changing the base
pkg/server startd/duration attribute from "child" to "contract",
but the core problem - svc.startd leaking memory in case of such
unlimited restarts - is still in place. Also, for the past ten
minutes or so since I fixed the pkg/server, the restarter hasn't
released a byte ;)
