ACTUAL BEHAVIOR
---------------
OTA Player spawning many idle sessions


Customer is seeing constant growth in the number of sessions attributable to the ota.player.server.PlayerAM module.
The number of sessions seems to grown until it exhausts the number of available session in the database.
It seems as though once a session is started it does not let go of the session and the only way to do so is to bounce the web server and oc4j oacore processes.
Manually killing the sessions in the database does not seem to relieve them either.

Customer has four self service nodes, each one has 6 oacore processes. Customers database has 4200 as the sessions parameter.


STEPS
-----------------------
The issue can be reproduced at will with the following steps:

Customer is seeing that each OC4J oacore has a single process. And that each process has close to 100 sessions...and that the number of sessions per oacore it growing for no apparent reason....
