There are a number of ugly issues it could be hitting. Filling up low
memory splits with page-table entries for the huge array is the first
thing that comes to mind. But I'm not that familiar with the VM stuff.
I don't think you've told us exactly which kernel you are running? If it
is a fairly recent stock kernel, you might consider bringing up the
issue on the kernel mailing list. If it is a RedHat or other vendor
kernel, you should talk to the vendor. And if it is an old stock kernel,
you should try again with the most recent 2.4.23-rc release; significant
improvements have been made in the VM.
