Ok Sarma, This would be a case of bug "5947623 - PGA MUCH OVERALLOCATED THAN PGA_AGGREGATE_TARGET". Best is to have the SR guy check for this, so that they can rule out this possibility also. alvaro We submitted all the 10046 Level 12 trace files to SR, they came back with nothing. thats why I am looking for ideas to where to look and ways to reproduce the issues.
