WARNING: VIMAGE (Virtualized network stack) is a highly experimental feature.

[NewtonRob]

I get the subject from: dmesg | grep -i warning

Is this normal? I'm having random reboots and would like to know if this could be causing problems.

I am running:
FreeBSD freenas.local 11.3-RELEASE-p6 FreeBSD 11.3-RELEASE-p6 #0 r325575+d5b100edfcb(HEAD): Fri Feb 21 18:53:26 UTC 2020 root@tnbuild02.tn.ixsystems.com:/freenas-releng/freenas/_BE/objs/freenas-releng/freenas/_BE/os/sys/FreeNAS.amd64 amd64

I am running a jail with Plex Media Server (beta).
Version 1.18.9.2578

I have received: freenas pcib0: _OSC returned error 0x10
Although I have added the tunable: hw.pci.realloc_bars=1 type Loader
I think this has resolved this issue. But may be too early to tell.

I currently have a pool called Red1 which has 4 4TB WD Red drives.

I tried it import a pool called Blue1 which has 8 1TB WD Green/Blue drives. system crashed and would not start until I used a previous boot image.

I know Blue1 is good as I copied most of Red1 to it before I reinstalled FreeNAS. Blue1 is in a z2 config.

I wouldn't worry about it. Been like that for many years. It's not enabled by default, but there are lots of people running with no issues. Here is some more info:
