Hi Kon, I believe that you are coming up against a bug in ipvsadm 1.25. There are several options available to resolve this: 1) Obtain the latest sources from svn # svn checkout http://svn.linuxvirtualserver.org/repos/ipvsadm/trunk 2) Obtain the first revision to include the fix for this problem from svn: # svn checkout http://svn.linuxvirtualserver.org/repos/ipvsadm/trunk@64 3) Apply the patch below 4) Compile ipvsadm without netlink support - Most easily achieved by compiling without libnl installe - This also disables IPv6 support >From 34c033ca687705068542dbc8f202a170706dc228 Mon Sep 17 00:00:00 2001 From: wensong <wensong@36f5d8da-7431-0410-8ca5-ec586ed2521a> Date: Wed, 21 Jul 2010 23:50:58 +0000 Subject: [PATCH] This fixes what appears to be a typo in the netlink client code whereby the activeconns is read as activeconns and then overwritten 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.
