Asi bude memory leak v ZFS. bsd je to 8.3
To se samozrejme vyloucit neda - poznas to snadno - kdyz po restartu
(a nejake dobe na pocatecni ustaleni) bude to cislo mensi - a postupem
casu bude pomalu a vytrvale rust, pak je tve podezreni nejspis spravne.
vytrvale to neroste povetsinou se to flaka mezi 5 - 5,5 GB z 8.
A kdyz uz to budes stejne restartovat, tak nejdriv postrilej vsechno
co tam bezi (kroem toho, co ti zajistuje prstup pres ktery to
strilis). Potvrdis nebo vyloucis moznost, ze tu pamet zere nejaka jina
aplikace a ne ZFS.
po restartu je tam hodne malo wired < 1 GB a pomalu to roste. Na netu
podeziraji ZFS z memory leaku casto. Zajimavy je tohle:
zfs-stats -M jen nevim co je ta kernel memory map. Prece ty gigabajty
nekde naalokovany byt musi pokud to neni overhead zpusobeny fragmentaci
pameti.

Taky se muze spodivat co najdes v
vmstat -m | grep solaris
Mam dojem, ze to prvni cislo je ve ctyrkilovejch strankach a jestli ti
po vynasobeni vyjde zhruba to, co vidis ve Wired, tak vis, kde ta
pamet je. Teda, z hlediska systemu. Stale nebudes vedet, kde se toula
v ramci ZFS, ale alespon neco.
vmstat -m vraci samy maly cistla, rozhodne ne neco co sezere 3 GB.
