Agent sessions are now stored in CTS. Currently AM is configured to never clear down these session. Over time this continual build up of sessions in CTS can cause instability and in the worst case an outage due to lack of resource.
A setting is available in AM: com.iplanet.am.session.agentSessionIdleTime
This setting is not enabled by default/set to 0. The request is to enable this setting by default/OOTB and set to an arbitrary value to prevent agent session build up and service protect the implementation - perhaps 1440 minutes / 24 hours?
