RE: kolccst obj: large streams pool memory segment

Did you search Metalink for "kolccst obj"? It reports several bugs related to memory leaks in Streams.

Subject: kolccst obj: large streams pool memory segment  

Anyone know where I can find more information about this KOLCCST object? And other KO objects for that matter?

SQL > select * from (select * from v$sgastat where pool = 'streams pool' order by bytes desc) where rownum < 6;

POOL         NAME                                          BYTES
------------ ---------------------------------------- ---------- 
streams pool kolccst obj                              1987055480 
streams pool kol raw                                   465430552
streams pool kolcalm coll                              464969704
streams pool koicnfadt adt attr                        419245184
streams pool kol vstring                               259053352 

Kinda curious why we are eating so much memory. This is a downstream database, so I expect to be using the Streams Pool. Perhaps there is a perfectly valid reason for this, and in that case I would like to learn about it.
