I'm running your test on pretty low-end h/w (i386, 1GB of RAM, two cores)
and cannot reproduce the problem for few hours now. The only tuning I did
was to set vm.kmem_size to 1GB. You still need to do this very tuning even
on amd64.
Could you post output of:
# sysctl vm.kmem_size
# sysctl vm.kmem_size_max
# sysctl vfs.zfs
# zpool status
# zpool list
# zfs get all <your_test_fs>
And place /var/run/dmesg.boot somewhere?
