That sounds like a potential hole birth issue. You might consider upgrading to at least 10.4 or 11.1 and re-trying the send; these added the vfs.zfs.send_holes_without_birth_time (default true/1) tunable to avoid "numerous hole_birth bugs". See this [1] commit. - Eric [1] https://svnweb.freebsd.org/base/releng/10.4/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/dmu_traverse.c?revision=308086&view=markup On Tue, Oct 1, 2019 at 5:51 PM Shiva Bhanujan <Shiva.Bhanujan@quorum.com> wrote: > Hello, > > This seems to be an older email, but I seem to be hitting this in FreeBSD > 10.3.
