Simple Calc All Script not creating blocks?

Hello,

I am trying to run a calc all to see how large my application is in PBCS.  However, when i run the script below, no blocks are being created and it eventually times out.  I can run a simple agg and can see new blocks being created as the script is executing in the DB statistics tab.  I am doing a level 0 import before i execute the script.  I am really stumped on this one...

SET UPDATECALC OFF;

SET AGGMISSG ON;

CALC All;
