Assuming that IPSO's behaviour is typical of BSD, the "free" memory is
different from the available memory.
Much of the memory may be used as cache - in-RAM copies of recently
accessed files and similar data. If a process wants to see the file,
the request can be serviced immediately without a disk seek. If, on the
other hand, a process needs more memory, the cached file information can
be instantly wiped, and the memory allocated to the process.
Per FreeBSD's FAQ:

EM
"free memory is wasted memory"
Hope that helps a bit.
Cheers

> Subject: [FW-1] Question on memory usage for Nokia firewalls
>
> Greetings:
>
> I've noticed that all of my Nokia firewalls are running at
> about 90-95% for memory usage. The load is very low on these
> firewalls, and some of them are hardly even active. Yet all
> of them report very small amounts of free memory.
>
> Here's an example:
>
> Memory Utilization (KBs)
> Total Real Memory 262144
> Active Real Memory 251264
> Free Memory 10880
>
> This tells me that out of 262,144 Bytes (256 Megs of RAM), I
> only have 10.6 Megs of free memory. Now this is on the
> inactive node of a VRRP cluster, so it's not passing any
> traffic. The Load is very low at 0.26.
>
> Is this normal behavior is am I having some sort of memory issue here?
