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 [....] Regards Raul
