Error in Amorphous cell construction

Dear All,

I am getting an error while packing the species in the cell. I tried multiple times by changing various settings like Force Fields, loading steps etc. But nothing seems to work.

The error says: Amorphous Cell calculation complete
                         Status: Error
                         Error description: Ran out of memory

Previously, I have made cells much bigger than this. This is a very small cell as compared to my previous simulations, but still i am getting this error. Please help.
