Well, I don't think it will hurt, but it didn't fix things.
I tried using ipvsadm while throwing lots of connections at the LVS host:
# ipvsadm --list --rate
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port CPS InPPS OutPPS InBPS
OutBPS
-> RemoteAddress:Port
TCP 192.168.55.60:http 0 52619 0 3578025

Notice that ipvsadm reports "02 for connection rate too, so it looks
like the problem is in (lib)ipvsadm.
Now, net-snmp-lvs-module-0.0.4 comes with ipvsadm v1.24 and I see v1.25
is available. However, I've failed to get net-snmp-lvs-module to build
with ipvsadm 1.25 on CentOS 5.4
make -C libipvs

I've installed libnl-devel, but it doesn't contain those files in v1.0.
I've also tried building libnl v1.1 but that won't build on CentOS either:
rpmbuild -ba libnl.spec

Any ideas how I might take this forward?
