Segmentation fault: address not mapped to object at address

[liuzg-23]

Hello,
I solved the real system of linear equations using mumps solver on a computer clusters. When I solved a small-scale (1000,000 unknowns), it worked. However, when I solved a large-scale (9000,000 unknowns), the code reported an error:
.....
Calling MUMPS direct solver

Can you help me solve these problems? Thanks very much.
