So 64bit has been the recommended way to go.. We run 64bit on most machines cuz they've got more than 4 gig ram. (And any besserwissers about to sound of about PAE kernels can kindly do so in another thread cuz I'm NOT listening!) As an aside, I hadn't heard of issues with 32bit xfs but in retrospect it can see the logic in it: a lot of company-supplied code has had 64bit issues cuz it came from a 32bit environment, but SGI was never "most companies" :-)
