PC 2019 (NAS)
After some experience with a small Synology NAS, and experencied the blue led of death (fortunatly solved), I decided to move to my own hardware supporting ZFS with Raid 5. - yves

Issues
Memory
Memtest86
- test DR 1600 / 1.35V
- bank A alone => pass
- bank B alone => pass
- bank A+B => pass
** Does not seems to be an issue **
For History
Memtest86+
=> system stopping, after 2s in memtest86+. 5.01
- Tried to change set memory in bios:
- DR 1600 / 1.35V => failed
- DR 1600 / 1.5V => failed
- DR 1333 / 1.35V => failed
- DR 1333 / 1.5V => failed
- Next step, test ram individually.
- ram 1 : 8Go => failed
- ram 2 : 8Go => failed
- Removed additional sata card => same Maybe an issue with Memtest86+
using 16 Gig (8×2) DDR3L 1866 RAM. Like I already said, it seemed to work, but under heavy loads I got random kernel panics (Kernel 4.18.20), usually SMP NOPTI and sometimes even more spectacular blow ups. I was thinking bad RAM module? Anyway, I pulled a module and ran 8 Gig with the result that I cannot kill it with any load. A quick check of the Intel J3455 Datasheet says only an 8 Gig MAX - issue
I have since read that the board might not be automatically powering the RAM or the RAM is not quite right. A possible fix might be to take the board out if AUTO and increasing the voltage or lowering the speed. I have not tried this
LAN Realtek RTL8111GR issue with default driver when too much load
To solve this problem you have to use the official Realtek r8168 driver instead of the r8169 driver, which is included in the Linux Kernel.
$ lsmod | grep r81 # check driver present
# default install gives =>
r8169 81920 0Easy fix (reboot to activate)
** 8.045.08 - Still crashing on heavy load with this driver ** => may be this is not the real issue
$ sudo apt-get install r8168-dkms # force support of that driver
<reboot>
$ lsmod | grep r8168 # check presence
r8168 524288 0
$ sudo ethtool -i enp1s0 # check if ethernet card is using the right driver

After ubuntu upgrade ? to OS: Ubuntu 22.04.3 LTS x86_64 / Kernel: 5.15.0-87-generic NAS does not stay shutdown. It wakes up alone if left on the Network (even without magic packet).
What I tried.
$ sudo ethtool -s enp1s0 wol g # was already setup, but why not
$ apt install wakeonlan # on NAS, again why not -> https://askubuntu.com/questions/1244785/trouble-with-wakeonlan-with-ubuntu-20-04/1265149#1265149Then Shutdown, wait and see..
