Yeah run the memleak24 posted above, and that should print some leak nodes (instead of numnodes 0), and the exact place they were found.
We are also tracking a problem with raidz, which is turning out to be really mischievous.

That output was from the memleak24 version...

% zfs version
zfs-2.0.0-rc6
zfs-kmod-macos-2.0.0-rc6-3-gbd2d850a38-dirty
I'll grab another dump to make sure.
Edit: BTW, both pools are RAIDZ, one is just a single RAIDZ VDEV, the other is two striped RAIDZ VDEVs.
