wow! I've been seeing this, too, but I thought I was just reading something wrong. Especially after my nightly cron jobs (which involve a 'find /') run, I'll often find myself with 80% of physical RAM used, and nobody (as far as 'top' can see) using it. You didn't specify which kernel you're using, but I'm running 2.4.19-rc1-ac1 plus some patches, and I've seen it since at least about pre9-ac*. I might try to narrow it down more if it could be useful.
