That would make sense, based on the behavior described.

Yes, but it was much more acute with parallel jobs.  IIRC, vmem is
enforced on a per-node basis, whereas mem is enforced as an aggregate
across the entire job.  That was exacerberated by PBS and Maui/Moab not
agreeing on what mem meant; the schedulers were assuming mem was a per-
node quantity.
