freebsd stable - May 2007 - Change in memory tracking in recent 6-STABLE?

Hi there,

I'm using symon to monitor memory usage among several FreeBSD machines.
After updating to a recent 6-STABLE, the amount of memory no longer adds
up to the total physical memory. The "inactive" counter is way too
small.

Which recent changes could have caused this? Is it a bug in symon or in
FreeBSD?

An example of the difference can be found here:

As well as "active", "inactive" and "free", there
is "cache", "wired"
and "buffers".

Check the following sysctls:
vfs.bufspace (bytes)
vm.stats.vm.v_active_count (pages)
vm.stats.vm.v_inactive_count (pages)
vm.stats.vm.v_wire_count (pages)
vm.stats.vm.v_cache_count (pages)
vm.stats.vm.v_free_count (pages)
