--------------------------

Buti there is a load balancing problem. When I look at the rule ststistics. I see an aoutput like this:

-------------------------------------

Name: Hits: Wgt: State: Ld: KAlive: Conn: DNS:

----- ----- ----- ------ --- ------- ----- ----

HomeDeck_Cluster-9001-1

1,494 S-1 Alive 88 TCP-9001 1 0

HomeDeck_Cluster-9001-2

1,797 S-1 Alive 2 TCP-9001 0 0

HomeDeck_Cluster-9001-3

141 S-1 Alive 2 TCP-9001 2 0

HomeDeck_Cluster-9002-1

1,359 S-1 Alive 2 TCP-9002 0 0

HomeDeck_Cluster-9002-2

298 S-1 Alive 43 TCP-9002 0 0

HomeDeck_Cluster-9002-3

80 S-1 Alive 2 TCP-9002 0 0

--------------------------------------

As you see, there is a load and hits problem.

How can set an homogeneous load and hits?

Re: Hits Problem

when using sticky option you are never guaranteed to get equal load.

Especially with sticky srcip as with NAT many clients can come to your vip using the same ip.

You can try to change the balancing method to 'leastconn' but be aware it will probably not solve the problem because of stickyness.
