Hello, (Sorry for sending this message twice, my previous message was in HTML and not plain text, please ignore it)
My setup is the following: CPU: Intel(R) Xeon(R) CPU X5687 @ 3.60GHz NIC: Intel 82599EB OS: Ubuntu 10.04 64-bit with kernel: 2.6.32-40 driver: ixgbe 3.22.3 , which I compiled and installed from source. There are two physical interfaces on the NIC: eth0 receives 3 Gbps and eth1 receives 5 Gbps of traffic (maximum traffic). No traffic is transmitted. The ixgbe driver is loaded with all the default parameters. I see packet drops, the number rx_missed_errors in "ethtool -S eth1" is increasing. This happens only on the eth1 interface from time to time, when the total traffic exceeds 7 Gbps. At that time, the CPU usage of ksoftirqd process increases at 100%. Also, ethtool -a eth1: #:/usr/src# ethtool -a eth1 Pause parameters for eth1: Autonegotiate: off RX: on TX: on and ethtool -S eth1: NIC statistics: rx_packets: 37835863761 tx_packets: 3 rx_bytes:
