This could be an issue that was solved though, I think I remember people complaining about FF. But when FF starts paging the easiest is to reboot. Yes, it has to do with hella tabs open after a month or so. :) FreeBSD servers are running 32gb or 64gb RAM and those have not been paging. That i've noticed. -- Waitman
