TrueNAS Core disconnects when proxmox backup is performed

[DiscipleOfMidas]

Hello all!

Here's my current setup:

I currently have an HP Thinclient T620 that runs TrueNAS-12.0-U8. So, I know it is discouraged to use Hard drive enclosures in Truenas but unfortunately that's the current setup. I have 3 servers that connect to the Truenas NFS share that I created (Current pool is a mirrored configuration with 2 Hard drives.) The Truenas NFS share is the storage of the Virtual Machines I'm running on those 3 servers. Usually each server has 1 VM running only.

Everything works fine, albeit a bit slow, which is fine. The problem is when I do backups of the VM via proxmox... So, in addition I also have another Striped pool which comprises of just a 1 TB external hard drive that I've also set up an NFS share with. Supposedly Proxmox backs up to this striped NFS share but whenever I do that I get this error...

Code:

truenas local dhclient 678 send packet no buffer space available
truenas local dhclient 678 network is down

When that happens the network goes down and I can't even ping the Truenas host IP. This ONLY happens when I do backups of the VMs to the striped Truenas NFS share AND when I attempt to migrate the storage of my VMs to local storage instead of the mirrored NFS share...

Any help is highly appreciated, Hardware is down below. Thanks!

Also, I'm planning to build a dedicated NAS server so this "jank" setup won't last long. I just need backups and vm migration to work
