kernel panics (Monterey)

This happens randomly but I've only experienced when multiple zfs commands are run from a script. Something like:
Code: Select all
sudo zpool create local ./file1.img
sudo zpool create remote ./file2.img
sudo zpool create gh ./file3.img
sudo chown -R hamid:wheel /Volumes/local
sudo chown -R hamid:wheel /Volumes/remote
sudo zfs create local/normal
sudo chown hamid:wheel /Volumes/local/normal

cp ~/tmp/tunnel.log /Volumes/local
cp ~/brew_installed_formulae.txt /Volumes/local/normal
sudo zfs snapshot -r local@macOS1
sudo zfs send -Rwc local@macOS1 | sudo zfs recv -v -F remote

cp "1.jpg" /Volumes/local/normal
sudo zfs snapshot -r local@macOS2
sudo zfs send -R -I local@macOS1 local@macOS2 | sudo zfs recv -v -F remote

cp "2.png" /Volumes/local/normal
sudo zfs destroy -r local@macOS1
sudo zfs rename -r local@macOS2 local@macOS1
sudo zfs snapshot -r local@macOS2

sudo zfs send -R -I local@macOS1 local@macOS2 | sudo zfs recv -v -F remote
