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.
