Calibre extraction memory issue

I have problems when using calibre xRC to do parasitic extraction on my chip. At the beginning, I do the job in the following step:
1. use calibre -lvs to create phdb file
2. use calibre -xrc -pdb to create pdb file
3. use calibre -xrc -fmt to format netlist

However, in the middle of extraction, the tool complained short of computer memory and stopped.

Then I tried the following steps:
1. use calibre -xrc -phdb to create phdb file
2. use calibre -xrc -pdb to create pdb file
3. use calibre -xrc -fmt to format netlist

The tool completed the first 2 steps but had an error in the 3rd step. It asked for a xdb file for cross reference.

My question is:
1. Do I have to use -lvs option to create phdb and xdb files?
2. If I use -xrc -phdb option to create phdb file, how do I get xdb file?

Thanks very much
