If I power cycle the server, I can run the replication script manually.
The script will go automatically again for another night or two,
before hanging up.
I've piped all output to a file, and there isn't any prompt for user
input, and the zfs receive on the remote side is un-killable (and
hangs the server when trying to restart).

It appears to be the receiving end choking on a snapshot, and not
allowing any more to run.
Once one snapshot freezes, running another (for a different file
system) zfs send/recv will just stall, with another un-killable zfs
receive.
