Hardware and Performance / Re: Opnsense LAN interface going down
« on: November 23, 2020, 08:54:10 pm »
Thanks for your response chemlud,
I have tried a brand new install, and that is what I am using now, but that doesnt seem to have had any affect. I am also not using suricata, and am just running a base install with the prometheus exporter added. I am planning to try another Intel NIC, and have a i350T2 on the way, but was hoping I could find a log or something that would give me some useful info about what was going on in the mean time.

Hardware and Performance / Opnsense LAN interface going down
« on: November 23, 2020, 07:24:56 pm »
Hello, Im really hoping someone can help me out with this issue, because it is driving me nuts!
I am running Opnsense (20.7.5) on a Dell optiplex 3020 SFF desktop( 3rd gen I3, 8GB ram 256GB SATA SSD ). I am using the onboard NIC as my WAN interface, that connects to my Virgin Media Router in modem mode. I have also added an Intel NIC ( I cant remember the model number now but I think it is a Pro 1000T) as my LAN interface. My setup is really uncomplicated from what I can tell, but for some reason my LAN interface goes up and down at random times.
Lastnight it was down for 6 hours while we were asleep, but today most of the day I could use it with no noticeable issues, but then it dropped again while someone was in the middle of a Zoom call this evening.
I have checked dmesg and can see the interface go Up / Down, and can even see holes in the metrics I am getting from OpnSense, but still can work out a cause. I have even tried three different switches connected to the lan interface to see if they were the problem, but still no dice.
Some relevant (I hope) output is attached, and I would love to hear any suggestions.
While posting this output, I have noticed that dmesg,today contains output for a reboot I didnt realise happened, also there are a lot of messages for

pid 90870 (syslog-ng), jid 0, uid 0: exited on signal 6 (core dumped) that I will have a look into (the syslog messages seem to be more to do with the reboot, than linked to any of the up/down of the interfaces).
