I have a CSS 11503 running ver 7.50.1.03 and I have an issue with load balancing. The connections seem to be hitting more to one server than the other. I have listed today's stats. Yesterday they were reversed where ps90prod4 was hit more. From the "show rule" command, the balance is Round Robin (default). I have also listed the config's for the content rules. Is this configured correctly for Round Robin? If so, why are they hitting one server more, then switching the next day and hitting the other? Thanks

this is the result of using sitckyness.
Especially with a mask like this.
If one subnet is more active than others, you will see more quest to one servers.
sticky-mask 255.255.240.0
advanced-balance sticky-srcip
Try changing the mask to a 255.255.255.255 and see if that helps.

I changed the advance balance configuration to arrowpoint-cookie. While this has resolved my issue with loadbalancing, I now seem to have an issue with clients being stuck to the server. When I do a "sh sticky-stat", I see that there are no sticky entries and users are being kicked out the their sessions but I have several connections to the service. The People Soft program we are using needs several ports open to connect for different reporting and management uses so I opened them with the content rule-prod2 but need the clients to be stuck to port 8080 which is the reason for content rule-prod. Here are the configs and any help would be grateful.
