what should I try?
- ethtool -K eno1 gso off gro off tso off
- kernel option pcie_aspm=off
- kernel option intel_idle.max_cstate=0 processor.max_cstate=1

Just to note, this is desktop hardware and you will probably never get server grade stability and performance from these desktop computing components, not build for 24/7 server loads and not tested to run with Linux from the vendor (Gigabyte lists only Win10 for this mainboard).

I really recommend to use server grade components, there are reasons why server hardware is more expensive.

sure, but for the cluster - its great, cheap and pretty fast. why not?
but, anyway, I had similar problems even with server hardware, like DELL or HP's.

so, ideas ? =)
 
Hi all.
Having similar situation EX62-NVMe from Hetzner sometimes giving me such error in log files:
https://pastebin.com/Vbd6C0ns
After that - server freezes, and I need to reboot.

pveversion
pve-manager/6.0-7/28984024 (running kernel: 5.0.21-1-pve)

Proxmox was installed on top of Debian 10 distro installed using Hetzner Rescue-System
 
Same issue here with a Lenovo TS430 and integrated 82576LM Adapter.

Only way to solve it is to reboot machine and then it will keep fine during a random number of days.
 
It seems that disabling TSO (tcp-segmentation-offload) and GSO (generic-segmentation-offload) works with
Code: 
ethtool -K <interface> tso off gso off

Any thoughts on how to make this permanent between reboots?

very old but making sure i help tie off this thread if someone else sees this

you got to edit your interfaces file on your proxmox host;
Code: 
nano /etc/network/interfaces

and add this to the bottom away from the other lines (BUT CHANGE YOUR NETWORK "eno2":
Code: 
post-up /sbin/ethtool -K eno2 tso off gso off gro off
