Hi Nigel,

I think that I have found the cause of the problem you are seeing.
Can you see if this patch to ipvsadm helps.

----------------------------------------------------------------------

Don't report persistentconns as activeconns

This fixes what appears to be a typo in the netlink client code
whereby the activeconns is read as activeconns and then
overwitten by persistentconns. The result is that the active
connection count reported by ipvsadm -L is wrong if the
code is compiled to use the netlink interface.
