Hello guys, We are having constant network issues in production in that the link goes down, waits *exactly* 7-8 seconds, and goes up again. This can happen zero to a few times a day on all our servers; they are not in the same location and are connected to different network devices.
Each server runs as a KVM virtual machine with 60 CPUs (Pinning) and 224Gi (Huge pages) - overall performance is excellent. The NIC is PCI passed through to the KVM machine AS IS. OS Rocky Linux 8.5, kernel 4.18.0-348.23.1.el8_5.x86_64 with Intel ice 1.9.11 built and installed using rpm. We have a traffic generator between two servers (our app: client+server) that is reaching 94Gb and can replicate this issue. The dmesg once the issue occur: Nov 28 16:01:27 SERVER kernel: ice 0000:00:06.0 eth0: NIC Link is Down Nov 28 16:01:35 SERVER kernel: ice 0000:00:06.0 eth0: NIC Link is up 100 Gbps Full Duplex, Requested FEC: RS-FEC, Negotiated FEC: RS-FEC, Autoneg Advertised: Off, Autoneg Negotiated: False, Flow Control: None Thanks, Assaf _______________________________________________ E1000-devel mailing list E1000-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/e1000-devel To learn more about Intel Ethernet, visit https://community.intel.com/t5/Ethernet-Products/bd-p/ethernet-products
