TrueNAS Scale 24.04/24.10 Flapping Network

Hi all,

Not sure where to ask or get help on this, but I have an old server running TrueNAS Scale 24.04 and the network interfaces seem to be flapping after a few minutes of stability. I have changed the cable, changed the port on the switch, and tried a different switch, tried a different port on the server, tried bridging ports. All to no avail.

This was fairly stable earlier on a Cisco C1000 switch, it has since moved to a dumb netgear switch, but this was after a hard power down and some moving.

I have looked at the logs and can see things dropping then a few seconds later starting back up, these are some of the common lines in the logs I have seen.

PS. I haven’t used these forms much lmk if I can provide more info, not sure how to go about continuing to troubleshoot this.

Do you have another card to try out ?
Other than that cabling or the one in there may be breaking down.
Or the new router has a bad port.
I don’t have much experience with networking but at times hardware brakes down and we don’t think of that can ever happen

The only success I had was on a managed C1000 switch earlier, I can go back to that, but I was hoping to not have to

Closing the loop on this, it appears to be a hardware issue sorry all.
