Snapshot schedule change in version 8 firmware

Since updating to 8.0.4, I've been getting the following emails every day at midnight which come from the array itself:

---

event: 8.3.65
time: Thu Sep  3 00:00:00 2015

Free space is below threshold of 15 percent for pool HybridPool. Default Snapshot Schedule will run with max-keep set to 1.
---

I don't have any snapshot schedules defined (never have). Looking in the eql logs, I see it says it scanned X number of volumes and 0 snapshots taken.

Is there a way to stop this new default schedule? I can't find it defined anywhere or even  place to stop these emails.

Thanks
