One of the odd things about this is that when looking at TOP or PS it
doesnt seem that much memory at all is being used; something like half
a gig where there is one gb of RAM available.

Check with `free` how much swap is in use as well.

And yes, I am running Ubu 6.10 (DD).

And their stock kernel? Have you checked for kernel updates? What version
are they based on, actually (`uname -a` should tell you this)?

Perhaps it would be best to compile your own kernel without any patches
and see if it's still the same behaviour.
