You're short of memory. Do a vmstat 5. If you see scan rates > 200-300 pages per second over a long period of time or scan rates > 5000 pages per second over a 20 second period of time, or if you experience pageout rates of >7-10 pages per second you need more RAM. See my comments from "Re: CRON in malloc(): warning: pointer to wrong page" Mon, 12 Apr 1999 06:54:00 for the long story.
