CSS 11000 Problem with load balancing

I have inherited a used Cisco Css 11000 from a friend. I am trying to set up a test environment to get a jump on my classes this upcoming semester. So far I have had no problems setting it up to load balance connections between four "servers".

But i started to notice something rather strange with it the other day. One server is getting alot more connections then the other three when i test. Here are the stats

Service State Conn Weight Avg load

test1 Alive 22 1 2

test2 Alive 52 1 2

test3 Alive 15 1 2

test4 Alive 142 1 39

So when i take test4 out of that content group the other three servers load balance fine. It is just when that one is in there does it do this.

Does anyone have any ideas on what it might be? Because I am totally lost.

  • Cisco Employee,

what kind of loadbalancing method do you use ?

Can we see the content rule ?
