I can't say no, is connected throught internet and run maybe some
poorly tunned services, but fairly difficult. The worst memory scenario
that I remember was artificially stressing zfs ... around 1.5Gb 'Inact'
and no swap in use. The box has 4Gb of memory and a 4Gb swap partition
enabled practically never used.

Given said that, and related to zfs the box 'constrain' kernel memory.
The loader.conf looks like:

[....]
vm.kmem_size="1536M"
vm.kmem_size_max="1536M"
[....]

This are normal figures from top, perhaps a little higher (wired) but
not much:

[....]
last pid: 90354;  load averages:  0.03,  0.05,  0.05    up 0+09:55:09
09:51:46
115 processes: 2 running, 113 sleeping
CPU:  2.3% user,  1.5% nice,  0.2% system,  0.0% interrupt, 96.1% idle
Mem: 356M Active, 2502M Inact, 873M Wired, 99M Cache, 399M Buf, 108M
Free
Swap: 4096M Total, 24K Used, 4096M Free
[....]
