Hi,



I am solving a Linear system with LU factorization. But failed with the following error.

Is there some suggestions on debugging this error? Thanks!

This appears to be inside MUMPS. I would recommend two things:

1) Get a stack trace for this error using the debugger

2) With that, also send a report to the MUMPS mailing list

  Thanks,

     Matt


The configure.log of PETSc is attached!
