Yes, the issue is running out of memory on long runs.
Perhaps some clean-up happens latter when the memory pressure builds but
that
is a bit non-ideal.

Hi Satish,
I have added these configure options
--batch=1 --known-64-bit-blas-indices=0 -known-mpi-shared-libraries=0

Matt,
Here is the process as it currently stands:
1) I have a PETSc Vec (sol), which come from a KSPSolve
2) Each processor grabs its section of sol via VecGetOwnershipRange and
VecGetArrayReadF90
and inserts parts of its section of sol in a local array (locarr) using
a complex but easily
PETSc configure is attempting to run some MPI binaries - and that is hanging
with this MPI.
You can retry with the options:
--batch=1 --known-64-bit-blas-indices=0 -known-mpi-shared-libraries=0
[and follow instructions provided by configure]
