Hi,

We currently have an LVS box(Ultra Monkey) box serving web requests to 
two real servers. Info as below :

ipvsadm-1.24-6
heartbeat-2.1.2-3.el4.centos
CentOS 4.5(kernel-smp-2.6.9-55.0.6.EL)

All was working fine this morning until I upgraded our OS and patched 
the kernel to kernel-smp-2.6.9-55.0.9.EL via YUM. After that users 
started complaining that they were being switched from one real server 
to another ie sessions weren't sticking. Nothing has changed on the LVS 
configuration.

Has anybody experiences an issue with this kernel causing LVS problems?
