# [petsc-users] DIVERGED_INDEFINITE_PC in algebraic multigrid

```Hi,

I am solving an inhomogeneous Laplacian in 3D (basically a slightly
modified version of example ex34).
The laplacian is discretized by using a  cell-center finite difference
7-point stencil with periodic BCs.
I am solving a time-dependent problem so the solution of the laplacian
is repeated at each time step with a different matrix (always SPD
though) and rhs. Also, the laplacian features large magnitude variations
in the coefficients. I solve by means of CG + GAMG as preconditioner.
Everything works fine for a while until I receive  a
DIVERGED_INDEFINITE_PC message. Before checking my model is incorrect I
would like to rule out the possibility of improper use of the linear solver.
I attached the full output of a serial run with -log-summary -ksp_view
-ksp_converged_reason ksp_monitor_true_residual. I would appreciate if
you could help me in locating the issue.
Thanks.

Michele

See the 'Profiling' chapter of the users' manual for details on interpreting output.
Phase summary info:
Count: number of times phase was executed
Time and Flops: Max - maximum over all processors
Ratio - ratio of maximum to minimum over all processors
Mess: number of messages sent
Avg. len: average message length (bytes)
Reduct: number of global reductions
Global: entire computation
Stage: stages of a computation. Set stages with PetscLogStagePush() and PetscLogStagePop().
%T - percent time in this phase         %f - percent flops in this phase
%M - percent messages in this phase     %L - percent message lengths in this phase
%R - percent reductions in this phase
Total Mflop/s: 10e-6 * (sum of flops over all processors)/(max time over all processors)
