panic: privileged instruction fault

[Ilmars Knipšis]

Hello!

This is binary install of FreeBSD 10 on Intel server board S1200 V3 RP 
with ZFS mirrored SSD disks for OS and ZFS RAID 10 with 4 HDD disks for 
data.

I am getting the kernel panic at random time almost every day:
panic: privileged instruction fault
panic: general protection fault
panic: vm_fault: fault on nofault entry, addr: fffffe046667d000
panic: page fault

Could it be faulty RAM ?



Small extract from core.txt:
