What do you mean by "wire"? I haven't heard that term in relation to vmstat before.

Again I don't know your system, but active memory is normally memory which has been used in the past 20 seconds (and perhaps a few other pages that waiting for disk operation to finish that somehow has exceeded 20 seconds). "free memory" is on the free list and can be reused at will. In between you have some stuff that is not free but hasn't been used recently either. Run this command line:
sleep 100000
and the process you create will be active for 20 seconds. After that, no it isn't free, nor is it active. I've seen inactive telnet sessions that last for months waiting the next command. When memory like this is freed, it tends to stay freed for a long time. Active memory is a real problem...you page it out and you will probably need to page it back in very quickly.
