Hello Everyone,

I’ve seen a few posts about this issue and I’ve tried a few recommendations found on other threads, but I’m still running into issues, so I‘be made an account to hopefully find people smarter than I for assistance.

My Hardware setup is:

-Mobo: MSI X570 Gaming Edge Wifi
-CPU: AMD Ryzen 9 3950x
-RAM: 96GB Oloy 3600 Cl 18
-GPU: Intel Arc A750 (Not really using)
- Storage: 870 Evo and Firecuda SSHD 1TB RAID 1 (boot
-Storage: 1TB NVMe for general use
-Storage 1x 8TB HDD and 1x 14TB HDD

I would like to use this machine to tinker with and run services out of, but I can’t seem to get the machine to stay available for an extended period of time.

I had TrueNas on it previously and don’t remember the whole system becoming unavailable.

I’ve turned off XMP, re-pasted the CPU, unplugged all external drives, changed cases, Memory tested (passed), updated all packages, stopped running LXCs and tried to run only VMs, ETC.

I can provide screenshots as needed, but I’m posting from my phone right now.

Any help would be awesome and thank you for taking the time out of your days if you have any ideas!

The local session also freezes, so it’s got to be a system issues, not “necessarily” a proxmox issue.
 
The classic way: remove all components until the nececary ones: psu, cpu, 1x ram, graphics if non is in cpu. then run memtest, stress tests. add one drive, repeat. add components one by one and run tests.
 
Some random hints, additional to @Supaman 's advice:
  • is the BIOS up to date? Verify that!
  • you already had run memtest. How long? Let it run at least over night.
  • how are the guests configured? Do you over-commit CPU cores, or worse: RAM?
  • you mentioned TrueNAS. Anything "passed-through" involved?
Not crash-related but important for reliability without data loss:
  • get some more storage devices to build mirrors and use ZFS :-)
To find the reason for those crashes examine the journal. If you run the system now and the previous boot had crashed then look into journalctl -b -1 -e. "-b -1" lists entries of the first boot before the current one. "-e" jumps to the end, to the latest entries. (See also man journalctl.) Search for error messages between the last line and (only) a few minutes before that one...

Thank you for reaching out!

I know BIOS is most likely not the latest.

Memtest was probably 3-5 hours in the first run (96GB)

Definitely far from over committing. I think I have a 6 cpu / 16GB RAM and a 2 cpu / 16 GB RAM

No pass through currently

I want some more storage, just wanted to get stability figured out lol.
