Metis Crashing

Hi there,

I've tried to partition a graph but kmetis or pmetis almost always crashes when I try to get more than, say, 15 partitions or so. For example, it crashes for sure with 28 partitions. Am I doing something wrong or is my graph incorrect? Could any one help, please?

The graph is attached below.

Cheers.
