[petsc-dev] Open file descriptors from -save_to argument on NetBSD

[Kevin.Buckley at ecs.vuw.ac.nz]

Hello again,

this follows on somewhat from my earliar posting regarding
initial experiences building and running PETSc for the
NetBSD platform.

Having built both PETSc and the application that uses it
for our NetBSD hosted OpenMPI/SGE grid, I have observed
that a large number of file descriptors are seemingly
remaining open on the compute nodes within the grid when
running the application.

I have determined that the file to which these descriptors
point is the one that is being passed to PETSc's "-save_to"
option.

I appreciate this may be something that's only being seen
on my platform but I'd like to remove the issue, if only to
be tidy.

In case there's some knowledge that might speed up my search
for a solution out there:

1) are there/have there been/ any known issues with file descriptors
not being closed within PETSc, for that file or otherwise, that
would inform this issue ?

2) which /routines/source code files/ would be the places to start
looking for clues ?

We are running PETSc-3.0.0-p7.

Kevin
