Why the OC4J instance CPU Usage still 99% even all user already Logout ?

Question

Hi All,
We are running OAS 10.1.3.3 with ADF BC Application.
At midnight when all user already logout, I notice that :
- on one instance, CPU keep on 99.9 %
- on the EM I see that there is there are 5 active sessions and 4 active request.
How can there are 4 active request while I am sure that I am the only one that login to the EM ?
I have tried to KILL -3 to create thread dump, but it doesn't work
How can I know, what are the those 4 active requests ?
What should I do to find out what consume the CPU ?
Thank you for your help,
xtanto

Finally...proof that I am not  going mad and that kglad's tweaks to his website make no difference at all to me.

Unacceptable CPU Use on Idle

Found in Version:
Flash Player 10              - 10_0_1_218
Affected OS(s):
Mac              - OS 10.5
Injection:
No
Steps to Reproduce:
« Hide
Steps to reproduce:
1. Create empty FLA
2. Publish as AIR or SWF
3. Install/run AIR app, or run SWF in Stand Alone player or browser
4. Check CPU usage in Activity Monitor 
  Actual Results:
  CPU usage of 3-6% on idle
  Expected Results:
  CPU usage of ~0% on idle
  Workaround (if any):
  None. Reducing frame rate reduces CPU use, but remains unacceptable even at 1fps.
This is a very serious issue, particularly for AIR applications. Having 3 or 4 AIR applications open on a Mac (a scenario that Adobe would like to see/promote) would use 10-20% of the CPU minimum, even when the applications are not doing anything. I also suspect that this is the root of at least some of the performance problems with Flash CS4 on Mac, as the stage core / swfPanel players are likely each using a sizable % of CPU even when idle.
