Hi,

I have a server which receive lots of events to it and when I do netstat -Ie1000g0, I'm seeing the errors as below.

If I saw right it is only the adapter e1000g0 showing errors? Checked the switch port for errors? Maybe try setting the switch port to speed auto or a fixed speed. Can also try to exchange the cable. If you have a spare adapter, maybe exchange it if nothing else helps.

Yes, it is only e1000g0. We did test the cable and it came out fine. We also tested the switch port and it was also good. I also just realised from the messages file that the NIC was detected failed at a random interval and that might be the cause? No sure why it is failing though

Maybe it is "simply" just not in order anymore - I'd try to exchange it vs. a new adapter and see if fails will still occure.
