I found out some duplicate rows in the view dbc.tablesize.
This rows have the same vproc, databasename and tablename but different currentperm.
Is there something odd, or I didn't understand that view's meaning ?
Since TD12.0 you should be using dictionary views with V suffix, e.g. DBC.TableSizeV. The backward-compatible views without the V truncate object names at 30 characters.
