i am not sure one can not tune it to stay up. it's just not clear how.
and that is the critical point.
on a 4g i386 with moderate+ load, my current parms are
vm.kmem_size=1500M
vm.kmem_size_max=2G
vfs.zfs.arc_min=120M
vfs.zfs.arc_max=900M
vfs.zfs.prefetch_disable=1
and it's up over two days, wooo wooo!
i suspect that i will next lower arc max.
