problem with the weight

[Octave <oles@xxxxxxx>]

Hi,
Working on 2.2.X with ipvs version 1.0.8 (size=262144) 
I have a cluster with 90-95 web servers (8000-10000 ActiveConn,
50-60Mbs) 
It worked fine with 60 web servers. I added 30 servers and
changed the weigth. Now the weight is the speed of the cpu
but the problem is:

starting lvs I have

[...]
FWM  15 wlc persistent 1200
  -> web1.XXXXXXXXXXX:0         Route   1000    13         9   
  -> web2.XXXXXXXXXXX:0         Route   1000   119        286       
  -> web3.XXXXXXXXXXX:0         Route   933    123        179       
  -> web4.XXXXXXXXXXX:0         Route   933    126        218       
  -> web5.XXXXXXXXXXX:0         Route   933    115        240       
  -> web6.XXXXXXXXXXX:0         Route   933    118        376       
  -> web7.XXXXXXXXXXX:0         Route   750    95         166       
  -> web8.XXXXXXXXXXX:0         Route   850    109        75        
  -> web9:XXXXXXXXXXX:0         Route   850    105        255       
     [...]
[...]

after a moment I realize the weight changed (!?)

[...]
FWM  15 wlc persistent 1200
  -> web1.XXXXXXXXXXX:0          Route   100    13         9         
  -> web2.XXXXXXXXXXX:0         Route   1000   119        286   
     [...]
[...]
