System Unexpected Reboots: Narrowing Down the Root Cause

[Kerros]

Hello All,

I'm having a frustrating issue currently. My system seems to randomly reboot and I'm trying to figure out why. I went around various forums trying a couple of fixes but have yet to find one that's sticking. I've already tried exploring:

• /var/db/system/cores
• /data/crash (empty)
• /var/log/messages

Nothing to indicate a software-related issue. My original thought was because of CPU overload but after watching carefully the highest I saw the load when running my only jail was 70%. Here are the system specs:

• Motherboard: Gigabyte GA-Z97MX-Gaming 5 Micro ATX LGA1150 Motherboard
• CPU: Intel Core i7-4790K 4 GHz Quad-Core Processor
• Power Supply: Corsair RM 650 W 80+ Gold Certified Fully Modular ATX Power Supply
• Memory: Corsair Vengeance 24 GB (2 x 4 and 2 x 8 GB) DDR3-1866 CL9 Memory (It is not a memory-related issue I've done testing with this already)
• Storage (OS): 512 GB SSD (for main OS)
• Storage: 12 TB WD Red HDD 5600 RPM

A few other observations:

• The issue is not related to Memory.
• The issue might be related to Power consumption?
• The issue is not due to overheating of any components.
• I've disabled S.M.A.R.T and Scrubbing on my SSD as I know that was a problem of 11.3 (I wanted to try it)
• No tasks running daily or weekly that I set myself at least that might be causing the issue (perhaps a default is triggering it?)

I would like some advice as to where to go from here. Thoughts?

The issue might be related to Power consumption?

Possibly power/sleep states. Try disabling everything related to power saving or "optimization" in the BIOS.

You don't mention a specific model. There were issues with a silicon motion controller/3D NAND in some brands/models and TRIM which essentially meant every scrub was showing up corruption.

Hm, I'll have to find that make/model of the SSD again then and verify.

I'll give the power/sleep states a check in the BIOS.

Reporting back: Still having the reboot problems.

Is it possible when writing to a HDD using a shared drive that it can crash the system?
