As per this suggestion I set this value to 2*8G:
vm.kmem_size="17179869184"

And bfore the kernel boots this value is set in the loader.
Tested it by goinginto the loader and show the value.

But once booted I still get:
[/boot] wjw_at_zfs.digiware.nl> sysctl vm.kmem_size
vm.kmem_size: 3718209536

So who is resetting this value???

Thanx,
