Strange enough, the servers all keep a weight of 1, all have about 30k
inative connections, and 3.4k active connections, but i can see that all
actual traffic (using mrtg), is going to, and commnig from the just rebooted
realserver.

Il see if i can replicate the behaviour later this week, and make some
snapshots of the mrtg stats.
