Odd 'auto' snapshots - what created them?

[furicle]

I recently updated an old FreeNAS box to 11.3u3
As long as I use the 'legacy' interface, it's all working great.

Except, I have a script that makes a snapshot, rsync's it elsewhere then deletes the snapshot. Occasionally it fails, and leaves behind a snapshot.
Before I upgraded, the snapshot deletion program cleaned these up for me when they aged out.
It seems like after the upgrade they aren't any more.

So if my script creates a snapshot called auto-20200604.0251-4d and doesn't clean it up, why isn't the period task deleting it?

Hmm - update to this. I don't think the 'rogue' snapshots were created by my script.

Is there any way the system itself could have created a snapshot? Does it do it for any reason other than the schedule?

Are you really running 11.3? Because there is no Legacy UI in 11.3.

Anyway, there was a bug that is supposedly fixed since U1:
