Hello,

I'm receiving the following kernel panic on my system, causing ZFS to become unstable. I'm fully up to date on the paid plan.

Code:

Any help you might be able to provide is appreciated.
 
Marking this as likely solved. I ran Memtest86 on the hardware and am getting a ton of errors, so it's hard to trust anything on the system. Hopefully the RMA hardware will help sort the issue out.
