Problem with weight 0 and reload : weight not modified

Hi,
 
I'm encountering a problem.
I modified the weight of two real servers (the LVS contains 4 realservers, all with initial weight at 1) like this :
 
>From :
        real_server 10.11.12.13 443 {
                weight 1
To :
        real_server 10.11.12.13 443 {
                weight 0

then I reloaded the conf (/etc/init.d/keepalived reload).
 
# ipvsadm -Ln|grep  10.11.12.13
  -> 10.11.12.13:443               Masq    1      23          47

Weight is not modified. I don't understand why. I had to stop/start keepalived on the backup node, then stop keepalived on the master, to have the correct behavior.
 
# cat /etc/debian_version
6.0.2

# uname -a
Linux s64lmwbiag8 2.6.32-5-686 #1 SMP Mon Jun 13 04:13:06 UTC 2011 i686 GNU/Linux

# keepalived -v
Keepalived v1.2.2 (08/29,2011)

# ipvsadm -v
ipvsadm v1.25 2008/5/15 (compiled with popt and IPVS v1.2.1)

Any help will be appreciated 
 
Cdt,
Sébastien ROHAUT
