Hah-ah! Yes, that certainly makes sense and is very plausible in this particular context. The db was created in 10g and has just been upgraded to, never used WM in it. I was doing a stats recalc on this very large partitioned table and was surprised it was taking a long time. So I decided to do a search on V$ACCESS just in case someone else was touching it. That's when I saw the "multi-versioned" object from my SID (95). Looks like all those multiple 11g stats-within-stats are being managed by WM. Interesting! Thanks for that insight.
