It's possible that a snapshot was *deleted* on the sending pool

created and I'm nearly certain of deleted.)
More information. The test I started this morning errored out
somewhat similarly, and one set of errors is clearly deleted snapshots
(they're 2hr snapshots that some of get deleted every 2 hours). There
are also errors relating to "incremental streams" which is strange
since I'm not using -I or -i at all.
Here are the commands again, and all the output.

cannot receive incremental stream: most recent snapshot of
bup-wrack/fsfs/zp1/ddb does not
match incremental source
That last error occurs if the snapshot exists, but has changed, it has
been deleted and a new one with the same name created.
That last message, which is not tagged as either warning or error,
worries me though. And wondering how complete the transfer is; I
believe the backup copy is compressed whereas the zp1 copy isn't, so
the ALLOC being that different isn't clear-cut evidence of anything.
It probably aborted the send.
