Same issue on 25.10. Problem seemed specifically around a VM directly sharing the nic with truenas. I was able to crash with minimal network traffic to the VM within a minute. I found either of these things fixed it:
once after boot (or as a boot task): ethtool -K eno1 gso off gro on tso off tx on rx on rxvlan on txvlan on sg on
or creating a bridged network of an existing device: Setting Up a Network Bridge | TrueNAS Documentation Hub " Converting an Existing Interface to a Bridge" then sharing the bridge for the VM.
As I mentioned, EITHER worked so I use the bridge method now and no longer run the ethtool command, so far so good.
It’s a bit weird then. I hadn’t had problem before creating the br0 and sharing to the VM&container.
I had problem communicating between VM&container and the host but didn’t had any crash.
The crash started after I created bridge and imported few VMs.
At the moment I just plugged a cheap TP-LINK pci-e card and bridge to the TP-LINK card and haven’t had crash yet(few hours). Before it crashed in 5 minutes after rebooting.
Any updates on which version to roll back to?
Keeps happening even with offloading (and all other options mentioned in the Proxmox forum thread) disabled.
Got the same issues get network hang errors, have now routet the VM to another NIC, also same nic (intel) and will se what happends.

I wasn’t willing to roll back so I purchased a NIC.

Just crashed again after a long time even though I used bridged network. This seems to reduce the issue but does not completely solve it for me.

Found some more detail into this issue from a 2016 bugzilla kernel report 118721 (idk why i cant post links)
Gonna try disabling TSO and see what happens
