  Are you running named or some similar caching domain name server on
Solaris? At this point, named eats up about 60MB on our BSD/OS server,
and you might not have been looking there for where your memory went.

  Otherwise, I'd say you've got a Solaris kernel bug. It should not be
possible for an application to allocate RAM from the kernel in a way
that does not get returned when the application terminates.
