That seems to work for the non-persistent services, but it doesn't seem to work
for the persistent ones. After removing a realserver or marking the weight as
0, no new traffic will be sent to that server, but looking at 'ipchains -L -M
-n' still shows masq entries for existing connections and those connections
don't seem to get routed to a new server until the masq timer expires. This is
with the Redhat 2.2.14-12 kernel plus the LVS 0.9.13 patch. (I've tried all the
earlier LVS patches down to 0.9.8 as well).

In my experience, if the realserver is removed from the configuration with the
ipvsadm command, then
the clients are switched immedietly. This may help solve your problem.
