Maybe I'm way off on this, but for session auditing, isn't there just 1 row per session? So for the most part, if the session ends properly, TIMESTAMP and LOGOFF_TIME should be the same. If these dates aren't the same, then the session abnormally terminated in some way.

Subject: AUD$ TIMESTAMP and LOGOFF_TIME are equal

Database on a 6 way RAC, each node has 16 CPUs.  (That's all the info I have on the system, I'm working remote)

Data collected from AUD$ via the DBA_AUDIT_SESSION view has the TIMESTAMP and LOGOFF_TIME equal for the vast majority of the sessions collected.  Which is not possible, some of these sessions did over a billion LIOs in what appears to be "no time".  

I've been searching Metalink and Google with no success on finding anything.  Anyone out there seen anything like this? 

Thanks much and have a great New Year!
