I wonder if this is related to PR https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194513 This is against "zfs recv" and hanging in process state "kmem arena" & but also has a workaround of allocating lots of memory in userland. But I do not see a lot of inactive with that PR. "zpool history" also hangs sometimes in "kmem arena" but I do not have a workaround for that. This PR is filed against 10-STABLE but confirmed against CURRENT too.
