Sorry for this fairly unhelpful reply but I shall go ahead anyway - Has it always been so memory heavy? The other night I was rendering a car scene (cad data that I exported from rhino myself) with a similar poly count that you mention, one minute it was rendering fine, very fast 'scene export' esq times etc.
Then I submitted it to the farm, hoping to leave and go drink fine belgian beers and all the machines failed, I couldn't tell why, so rendering locally I saw that it was trying to use all the 32gb of ram... I tried teaking the dynamic memory limits etc. but to no avail - so I tried deleting some geo that wasn't visible and it worked... (but it's not as though i deleted 5 million polys) Then in the morning despite my headache I tried to debug but it rendered fine with all the geo. So I just had mysterious 6pm problems.....
