[petsc-users] Tough to reproduce petsctablefind error

[Chris Hewson]

Hi,

I am having a bug that is occurring in PETSC with the return string:

[7]PETSC ERROR: PetscTableFind() line 132 in
/home/chewson/petsc-3.13.2/include/petscctable.h key 7556 is greater than
largest key allowed 5693

This is using petsc-3.13.2, compiled and running using mpich with -O3 and
debugging turned off tuned to the haswell architecture and occurring either
before or during a KSPBCGS solve/setup or during a MUMPS factorization
solve (I haven't been able to replicate this issue with the same set of
instructions etc.).

This is a terrible way to ask a question, I know, and not very helpful from
your side, but this is what I have from a user's run and can't reproduce on
my end (either with the optimization compilation or with debugging turned
on). This happens when the code has run for quite some time and is
happening somewhat rarely.

More than likely I am using a static variable (code is written in c++) that
I'm not updating when the matrix size is changing or something silly like
that, but any help or guidance on this would be appreciated.
