Recreate the Rollback Segments with a bigger MIN_EXTENTS. Oracle recommends
a MIN_EXTENTS of 20. Rollback segments are used in a circular fashion and
if a transaction commits, the segment is marked as re-usable. By making
bigger rollback segs you increase the time it takes until the segment is
actually reused. Check the manuals under "Read Consistancy".
