Have you tried clearing the cache to see the activity after it's cleared; not 
the best choice - as it could affect the response time, but...

There is No Aging happening .. Let us assume that u are Calling a Select
Stmt Again and Again with different Parameters to it and also same
parameters .. As Far as Oracle is concerened your stmts have not aged .
They are new since it has now only been created or it has been used in
the past few mins.

So oracle tries to create new space for the stmt that u are trying to
parse now and it fails there ..
