Hello list,
We experiencing lots of RX packets being dropped on LVS server.
Moving some high traffic VIPs to other LVS which reduced rate of packet
drops however not completely eliminated.
Anyone seen this issue or have insight into it ?
Configuration :
2 Intel Xeon Quad core processors, 8 GB RAM
Debian etch running 2.6.18-6-amd64 kernel.
heartbeat-2 2.0.7-2
ldirectord-2 2.0.7-2
Interface cards Broadcom BCM5708 Gigabit[ eth0 & eth1 are
bound
using bonding round robin configuration ] on a Cisco 3560 using group
channel.
VIPS : 15 (1 UDP, 14 TCP) all in Direct server return and WLB mode.
Real Servers : 79
Traffic : 120 Mb/s
Uptime : 1 day
ethtool -S eth0
