e1000e eno1: Detected Hardware Unit Hang:

Same errors here.
I see that proxmox has had problems with Intel NIC for many years.
What card should I buy for this to work properly?
Or maybe that's just the way proxmox is?
 
Also wanted to give a big thank you for

Disabling TCP checksum offloading worked for me

This seems to have solved the hardware hangups and DRASTICALLY improved the network latency for the webapps I am running.

Great! It helped! Thanks a lot!

I presume that you executed the command in the PVE node, not inside the VM, correct? Moreover, what other guests did you have in the node? I have a mix of VMs and LXCs and this behaviour only happens where I have VMs. Would that be your case, too?

Facing same issues after recent updates on 3 computes and different HW ! seems like something changed after update... system was stable for years before!

I am also having this problem, disable offloading is one way to solve it. Another solution is to modify your VM's network card model to Intel E1000E instead of VirtIO.
I was also able to reliably reproduce the problem with iperf3 client running inside the VM. (The following command might hang your host)
iperf3 -c <IPERF_SERVER> -M 100 -t 50

Thanks a lot for your report, @leiwang15 . Much appreciated.

Incidentally, I found this thread on these forums regarding E1000E vs VirtIO on Proxmox.
