Do you have the ability to run the latest 6.1 beta? If so, and your experience is like mine, the problem goes away. I'm running the exact same setup on 6.1b4 as I was on 6 stable and I don't see anywhere near the same amount of mem usage as I did before - in fact I've been able to triple some of my Postgres buffer settings with the 4G of ram not even 1/2 fully utilised. I saw very similar memory sizes with httpd as you reported before I switched to lighttpd (which interestingly did not have the same problem on STABLE 6 - always using around 17M) but some Python processes I was running regularly maxed out at over 1.4G, now it's down in the 400M range doing the same processing on significantly more data.
