I have a node that has been running for 6 years without any issues.
Recently, it started freezing randomly every few minutes or hours.

Recently, it started freezing randomly every few minutes or hours.
Hardware:
- Ryzen 3700X on Asrock X470D4U
- OS on SSD (ZFS mirror pool of 4 HDDs + 900P Optane)
Symptoms / Attempts:
- Initially freezes occurred every ~5 minutes.
- Reinstalled Proxmox VE 9.0-3; freezes now occur every few hours.
- BIOS: Disabled C-States, no significant effect.
- Tried different kernels (older and latest 6.17), no difference.
- Power supply: Tried a separate PSU for main system and drives, no effect.
- ZFS tuning: L2ARC/SLOG temporarily disabled; system still freezes.
- kdump loaded but no crash dump is created, indicating a complete hang rather than a kernel panic.
Other notes:
- ECC RAM (should report errors)
- ZFS is latest version from Proxmox VE
- No logs are generated at all; system just hangs completely.
Question:
- What else could be causing these sudden freezes?
- Could it be hardware-related, ZFS/tuning, or something else?
Any suggestions for debugging would be greatly appreciated.
