Errors on incoming interface Intel X520-DA2

Dredex

After upgrading to 2.6.0 I see errors on incoming LAN interface (Intel X520-DA2), My pfsense is monitored by Zabbix and this started after upgrading to 2.6.0
There are no errors on the switch interface (Brocade ICX-6450)

Hardware
CPU: E3-1230 v6
2 x Intel I210 on WAN
1 x Intel X520 on LAN with 8 vlans

Packages Installed:
acme, haproxy, iperf, mailreport, nmap, suricata, wireguard, zabbix-agent5

Other:
All Hardware offloading disabled

The red circle is when I rebooted pfsense

Beyond the error count are you actually seeing any connectivity issues?

Are you able to try switching the interfaces? (is it a dual port NIC?)

Have you tried a different DAC cable?

We have seen a number of reports of this, there is a thread here.
No solution as yet. No real confirmation it's actually a problem either, this could be real reflection of previously unlogged errors.

Just now changed from Brocade to a Mikrotik and different DAC cable, same problem...

We have active RDP connections to different clients and sometimes we get connection lost for 1-2 seconds.
We keep a live ping to these clients and there are no request time outs even when we get connection lost.

Mmm, some seconds loss is unlikely to related unless all the errors came at once. But that doesn't look like the case.

Hmm, I can replicate your setup very closely here but can't replicate the problem. Yet.

This is an X520 NIC connected as a LAGG to two 10G ports on ICX-6450 using Brocade DAC cables:

Are you able to test a different cable? I do have a lower cost DAC cable here that throws errors at 10G.
