Default TGrid Memory Issues

I have created a surface mesh of a complicated geometry in Gambit and exported it as an .msh file. I open it in TGrid 3.6.8 and create a nice 4 layer prism mesh and tetrahedral core. When I try to refine the tetrahedral elements TGrid crashes with the following memory error: "Error: Cannot allocate memory for id 8 (cell). Error Object: #f"

I am running on a Sun Cluster with 24 Gb of memory and 30 Gb of swap space, which should be more than enough.

Is there an alternative method to assign more memory for larger jobs? The largest successful mesh I can create are around 10 million cells, but I would ideally like to reach 20 - 30 million cells.

Any help would be appreciated.

Regards, Daniel
