We had a very similar situation running on HP-UX with ASMM enabled. It turned out our SGA was overly sized, and in this case, when the SGA was lowered, the problem went away. We were surmising that since Oracle thought it had a lot of room to work in, it didn't attempt to optimize. We worked on this for a few weeks, opened an iTar, and got nowhere. When we lowered the SGA to start tuning from the beginning again, it went away. This was the only change made.
