Rich,
Did anyone ever get back to you about this? I believe it is an issue
with how OpenPBS measures memory on Linux. There is a patch for OpenPBS
on http://www-unix.mcs.anl.gov/openpbs/ , which isn't currently in the
OSCAR version.
We have allied it, along with a bunch of other patches from there and
it corrects the problem.
