The error for missing replica catalog (for example, if included in the dax), is very misleading:
2010.11.22 20:53:50.439 PST: [WARNING] Replica Catalog is either down or connection to it was never opened
This warning should be changed to something similar to the tc warning:
2010.11.22 20:53:50.347 PST: [WARNING] The Transformation Catalog file /home/rynge/Pegasus/install/current/etc/tc.data was not found - Will consider only TC Entries from the DAX
