Rich,

Can you do a quick snapshot-type comparison of v$sesstat values for that
session (from another session of course)? This might show up Stats that may
show what's occurring... I have used STATSPACK can snapshot a _session_ but
don't have the details at the top of my head... (I think this is available
in the STATSPACK readme file).
