Definetively there is something strante in your database.
But I need more information
I think the best thing you can do is to trace, in the paper is the way you
can do it, then send it to www.oraperf.com
This really could give a good idea about what is happening in your database.
About your init.ora
Really I don't understand why you use 32k,
Personally I would created it to 8k.

What is a "VARIANT"? Sounds like a model of Ford, and that is
