Cleanup backupgroups, system objects

We assumed we had the dreaded "system objects" problem because we
were running 4.2.2.0, we have a bunch of Windows clients, and our
database was growing at a rate that we didn't like.

So a couple of days ago, we upgraded to 4.2.3, and ran CLEANUP BACKUPGROUPS.
It didn't seem to accomplish anything.  It finshed fairly quickly,
compared to some of the reports I've read here, and finished with the
message:

ANR4730I CLEANUP BACKUPGROUPS evaluated 28729 groups and deleted 0
orphan groups with  0 group
members deleted with completion state  'FINISHED'.


Somebody on this list suggested using the command
QUERY OCC * "SYSTEM OBJECT"

to get an idea of how bad the problem was.  I tried that, before and
after the upgrade, and got the same result: zip

tsm: UKCCSERVER1>QUERY OCC * "SYSTEM OBJECT"
ANR2034E QUERY OCCUPANCY: No match found using this criteria.
ANS8001I Return code 11.


This doesn't seem to make sense to me, because if I pick a client at
random and issue a query occ for that client, I see some system
object filespaces.

tsm: UKCCSERVER1>q occ grabthar *

The pieces just don't seem to be fitting together. What am I missing?
