FreeNAS 11.3-U4.1 box crashes (or loses connection) every day or two requiring hard reboot

[kentclark]

Apologies in advance for the vagueness of this issue. I have been tearing my hair out trying to find the root cause but I am still very new to FreeNAS.

I have been running my first FreeNAS box (hardware below) for a few months.

Nearly every day since it has been online it will crash/lose connection to everything and it requires a hard reboot to get working again. No SSH access, no web GUI access, no error in messages (/var/log/messages). Hard reboot at the box and everything runs fine for another day or two. The longest it has gone without needing a hard reboot is ~3 days. This will happen while Plex is playing a file, when it's been sitting idle for several hours. There doesn't seem to be a correlation.

Things I've tried:

• Combing through /var/log/messages but there's never an error (To be fair, I'm not sure if I'm looking in the right place)
  • I have poked through various /var/log/ folders but unsure if there's somewhere specific that would tell me
  • Have downloaded a couple debug logs but same story
• Editing bios settings to remove any power saving features

Things I haven't been able to conclusively rule out:

• Realtek NIC
  • This mobo has a realtek NIC which I've come to read is not recommended
  • Only one PCI-e slot which I use for the video card. Is it possible to remove this video card and swap for an external NIC if I sacrifice monitor output after install?
  • I wanted to try and determine a root error cause before buying a new mobo

I have attached the latest debug log. I had a crash last night around 11:25pm and restart around 8am this morning (about 11 hours previous of this post.)

If there is additional information that would be helpful please ask and I will provide it to the best of my ability.

After upgrading to train 11.3 I'm experiencing the exact same problem. Every day my mapped drive in Windows loses connection, which almost never happened with train 11.2
Furthermore the Plex jail does not have an update to 11.3, which I suspect could be the culprit, but I'm not at all sure.
I do want to downgrade to train 11.2 again, but I'm not sure how to do that
