[RC7] High memory usage - ARC ZFS relative

Hi,

I'm currently running the rc7 version of unraid 6.12.

My system seems to be very instable since the update (I was on rc6 without any issue).

   - GUI stop working correctly (no more realtime monitoring on the dashboard after few minutes).

   - Memory usage is very high

   - Arc limit size seems to not be taking in account (set at 1/8 of max memory, so 8 gig for 64 gig) using 24 gig after few hour on 64gig (see files).
