--- Comment #2 from Shiva <shiva.bhanujan@quorum.com> ---
Restricting the secondarycache=3Dmetadata param setting to the ZFS where the
snapshots are being received doesn't help this issue.  FreeBSD still crashe=
s w/
the same traceback.

zfs send -v -i <src>@<from_snap> <src>@<to_snap> | zfs receive -Fuvs <dst>

we're setting secondarycache on <dst>

zfs set secondarycache=3Dmetadata <dst>

Setting secondarycache to metadata on the entire pool makes the system
prohibitively slower.  this is a real showstopper for us, as we can't trans=
fer
snapshots for more than a day.
