memory problem

[Matthew Knepley]

Here "maximum memory" means all the memory that has
been PetscMalloced. Some of this might have been freed,
but we do not keep track. However, it looks like you are
trying to allocate 1G. Also, it looks like you truncated the
stack trace. Can you send the entire trace to petsc-maint at mcs.anl.gov?

  Thanks,

    Matt
