Load balancing issues

["Nicolas Chiappero" <Nicolas.Chiappero@xxxxxxxxx>]

Hello,

Can you explain the possible reasons that can
cause an ipvsadm ouput looking like this :

IP Virtual Server version 0.9.7 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port          Forward Weight ActiveConn InActConn
TCP  XXX.XXX.XXX.XXX:443 rr
  -> 172.22.1.105:443            Route   1      7          41
  -> 172.22.1.107:443            Route   1      3          44
  -> 172.22.1.104:443            Route   1      9          44
  -> 172.22.1.103:443            Route   1      8          38
TCP  YYY.YYY.YYY.YYY:80 rr
  -> 172.22.1.107:80             Route   1      25         1008
  -> 172.22.1.103:80             Route   1      28         1000
  -> 172.22.1.104:80             Route   1      25         1008
  -> 172.22.1.105:80             Route   1      36         993 
TCP  XXX.XXX.XXX.XXX:80 rr
  -> 172.22.1.103:80             Route   1      303        10573
                                                ^^^
  -> 172.22.1.105:80             Route   1      1392       9508
  -> 172.22.1.104:80             Route   1      1273       9188
  -> 172.22.1.107:80             Route   1      1330       9572

This director is a Linux box running a 2.2.14 kernel.
I cannot figure why 172.22.1.103 realserver is not having
the same number of active connections although I use round
robin load balancing and same weight on each realserver.
