Thanks Brandon, I did do a snapshot of the directory to see if there was any undo growth in the files over the course of time. However, nothing was showing activity. I'm wondering if I do have a rogue trace going on, will it kick in every time a session id and serial number match or should the trace have died when the session died?

One way to find out if a trace is currently being run is to check the most recent files in your user_dump_dest directory, but that's not a foolproof method since there could be a trace running, but no activity in the traced session, or there could be a trace being written to a directory other than your current user_dump_dest directory if someone changed the parameter temporarily or used other methods to write their trace file to a different location (e.g. I think you can do that with oradebug).

I am curious to find out how to identify if a trace is currently being run. Privileged/Confidential Information may be contained in this message or attachments hereto.
