Mandi! dorsy via pve-user In chel di` si favelave... Thanks to all, particulary to Victor for the wonderful analisys, that lead me to learn a bit better OOM dump...

ARC is a (indeed, complex) buffer/cache, so seems reasonably that, if i need to sacrifice something, it is better to sacrifice cache than VM. Aniway, if i understood well, default ZFS was to have ARC at 50% of the RAM; after PVE 8.1, PVE modify the default to 10% (for new installation); there's also a 'rule of thumb' to setup ARC, so 10% is somewhat a 'starting point'. In some server i can setup easily swap (i have a disk for an L2ARC, so i can simply detach, partition a bit and reattach as L2ARC and swap). Clearly, i'll set swappiness at 1, to be used only when strictly needed.
