I mean, ok: I got used to it, that small daemons like the

not wanting to defend this applet-mania :-) but you may be victim of
mapped-in stuff being reported more than once although it in fact
consumes memory only once (executable shared libs, eg).
Exactly. The fact that gnome applications and applets make such heavy
use of shared libraries means individually they look bad using
traditional 'high level' tools which don't distinguished shared from
private memory. But it means they are efficient when many apps use the
same library which needs only be mapped once for many processes or many
users of a modern multiuser OS
'pmap -x' may help identify those pieces of memory.
I just had a quick look at this. To be honest, this is the first I'd
heard that top was in opensolaris. I've always used prstat. But yes,
top does leak heap space:

When I try to run top with LD_PRELOAD set to libumem and UMEM_DEBUG set
to default, it exits with Abort. So chances are it's doing something
incorretly. Was this recently ported from Linux?
