Generaly, memory leaks are not hardware related. They're code related.
Either way, the only real way of isolating them is process of
elimination. Which means, turn down extra services, update OS, etc.
Since I doubt you can turn down any extra services without impacting
your users, upgrading to see if it goes away is the next simplest
without impacting everyone (other than for the reload of course).
You could also just search CCO or call TAC and see if there is a known
issue with that revision of code as well.
