8.1.6.3 shared pool

Got an old 8.1.6.3 DB running Siebel and  just this week been getting
4031s but don't see anything big in memory. 
 
    This is test DB, but copy of production with same initora except for
sps which I increased on Monday. 
 
increased sps from 100000000 to 
                   204800000 and got around first problem.
User says he's got new data, but not doing anything different.
He also  said he broke data up into smaller batches.
 
Now I flush the pool and it's still pretty well used
 
Ran
-- What is currently in the shared memory?
col name   for a40
col Memory for 999,999,999
select type
      ,name
      ,sum(sharable_mem) Memory
      ,kept
from v$db_object_cache
where type NOT IN ('NOT LOADED')
group by type
        ,name
        ,kept
order by sum(sharable_mem)
;
 
    But didn't see much using memory.
    What am I missing?
 
    TIA,
    Larry
