I've noticed an issue with rc2 which I'm not able to reproduce or prove easily but I'm providing this report in the hope that it might point the developers to the general area of interest.
I have a server with three ZFS pools and I've noticed since updating to rc2 from rc1 that one of my pools named ZFS has a random drive each night drops into a faulted state.
For example:

After rebooting the drive resilvers and operates as normal and is in good shape SMART wise.
Initially, I thought I just had a bad drive and planned to replace it but then I noticed that each night the failing drive was different.
Over 5-6 nights I noted that nearly all the drives in the pool had at some point been marked as faulted with no pattern.
Different brands of drives, different ages.
I moved all the drives over to a different backplane slot to rule out a connection issue.
The next thing I noticed is that the issue starts around 4:30-4:40am each day. If you check out the attached syslog which is a notepad I've been keeping each morning of the issues, the drive of choice that morning always develops the fault around the same time. I've checked all my apps and plugins and nothing is running at that time from what I can see.
Long story short, I've downgraded to RC1 and the issue hasn't happened since.
I hope this report helps in some way but I won't be offended if you need more or can't trace the issue.
