Any clues or things to look > at are very welcome. I wonder if the scrub has something to do with it? Are you in the middle of the scrub when noticing missing snapshots? Do they reappear after the scrub is done? The scrub seems like it's relevant. I take it you're doing a cron-driven scrub? If so, with what frequency? I'd normally push this along to the ZFS list, but given it's r151014 AND a non-updated r151014 at that, a bit more work here is probably a good idea.
