Hi Koen, please take a look to this archived mail that explains how
farmguardian and zen work.
http://sourceforge.net/mailarchive/forum.php?thread_name=BLU164-W39A7180399A764E10E6183C7280%40phx.gbl&forum_name=zenloadbalancer-support
And then you confirm us that after 30 seconds of recovery and with clients
trying to connect your problem persist or not.
